Bumped version to release Amber 0.6.4

* Prevent server side error with invalid base64 csrf token

* Return false once Base64::Error raised

* Fix test description gramma

* Add development pipeline

* Fix indentation

* Update pipe

The logger currently has a custom `puts` method that is not logging
correctly the severity.

This removes the additional method and uses the level methods instead.

* checks the current path a project name to make sure it doesn't contain a
space

* dynamic name

* Better error text. I think the logger stuff should be different though.

* added suggested improvements

* formatted

* Fix typo in index.slang.ecr

Update wording to proper English grammar. It's only a small change but adds to the overall polish of this already great framework. Will propose an equivalent change to the `index.ecr.ecr` template.

* Fix typo in index.ecr.ecr

Parallel to same wording change applied to `index.slang.ecr`

* Avoid minor error in 'db status' if there are no migrations (#522)

* Change 'dir' to MIGRATIONS_DIR (#526)

* move database initializer to new

* add require granite_orm/adapter/db

* remove blank line

This solves error that was being printed in the browser for woff2 fonts:

"Resource interpreted as Font but transferred with MIME type application/font-woff2"

* Minor fix

* Add stats config

* Change severity position

* Indent progname

* Add comment about server reload

* Add comment about browser reload

* cleaned up recent csrf improvements

* finished

* formatted code

* removed unintentional line delete

* Add file counter and reduce watcher logs

* Cleanup

* Add counter to the client watcher

* Fix log

Right now when running amber crystal specs it creates a lot of log
outputs which are not necessary.

- Disables the logging for specs

With these changes we should see tests run more cleanly.

This is a small enhancement change to follow Crystal Lang guidelines to
avoid unecessary memory allowcation.

See https://crystal-lang.org/docs/guides/performance.html for details

* [Pipe] Adds support for head requests

Issue https://github.com/amberframework/amber/issues/233

Currently head requests are returning 404.

- Does not render response.body if the request is of type HEAD
- Converts route.cr from class to struct this should give a performance
improvement
- Changes :get symbol to "get"

With the changes it will be possible to make HEAD requests and the
response.body should be empty

Example:

 ○ http -v HEAD :3000

Request
----------------------------
HEAD / HTTP/1.1
Accept: */*
Accept-Encoding: gzip, deflate
Connection: keep-alive
Host: localhost:3000
User-Agent: HTTPie/0.9.9

Response
----------------------------
HTTP/1.1 200 OK
Connection: Keep-Alive
Content-Length: 0
Keep-Alive: timeout=5, max=10000
Set-Cookie: amber.session=eyJfZmxhc2giOiJ7fSJ9--mpOMtKPrJi1R9nRQyYtmlwkX5CY%3D; path=/; HttpOnly
X-Powered-By: Amber

Current when using cluster mode is not passing the correct Amber environment 
to the forked processes. 

- Ensures forked processes start in the correct environment.

We this change forked processes will start in the correct environment.

* Add websocket routes to 'amber routes' output (#295)

- Show websocket routes in 'amber routes'
- Avoid string "<Time> Class |" that used to be printed in first line
  of output
- Fix issue where in case of Con::Troller, only "Con" would be printed
  in Controller column

* Add Spec tests for 'amber routes' command

* Fix indentation in 'add_route' helper

* Add spec for websocket in 'amber routes'

* Refactor 'set_route' in 'amber routes'

* Wrap 'amber routes' tests for default routes in describe block

* Makefile improvements

- Amber binary now depends on all its source files (src/**cr). If any file
  changes, just running 'make' will rebuild Amber. If no source files have
  changed, running 'make' will have no effect and will exit quickly.
  (One can always force make execution with 'make -B [target]', in case that
  forced recompilation is required.)

- Structure of the Makefile is now such that adding more binaries later is
  easier

- A couple "stylistic" improvements were made which don't affect previous
  behavior, but use more standard Makefile syntax and variables

- When running 'make install', if previous copy or symlink doesn't exist
  (as is the case on a first install), 'rm' doesn't fail with critical error

- 'make clean' now only deletes amber-specific files, not shards etc.
  This makes it easier/quicker to invoke 'make' afterwards and recompile
  amber without having to go through shards downloading again

- 'make distclean' deletes all files and brings source tree close to original
  state as would be after git clone

- Both variants of clean now only delete bin/amber and not bin/ as a whole,
  so they now correctly preserve 'ameba' binary which comes from shards and
  also lives in bin

* Minor Makefile simplification

* Makefile improvements

- Remove invocations of `pwd` where not necessary
- Add invocations of `pwd` where necessary
- Replace PREFIX?= with PREFIX=

(The removal of ? in PREFIX?= makes this setting not susceptible to
unintentionally taking the value from the environment variable.
The correct way to set PREFIX is by doing 'make install
PREFIX=/path'
(as opposed to 'PREFIX=/path make install').)

- Do not run link (which requires admin privileges) in default
  target (build)
- On install, remove destination file before copying the binary
  (solves problem when a symlink already exists and copying fails)
- Make build depend on lib/
- Run shards only once, if lib/ doesn't exist
- Better qualify $OUT_DIR
- Add missing echo

* Make link targets depend on build, just like install

Replace `` invocations with Crystal's API

Say "Connection unsuccessful" in case of CLI database errors rather than
"Connection refused". "Connection refused" was misleading because the
error may be application-based (e.g. wrong username or password, or
missing database) and so it is not related to system's ECONNREFUSED error.

Amber::Pipe::Static's initializer is inherited from parent class
and setting @fallthrough and @directory_listing options to false
in Amber did not have the desired effect of disabling them.

The solution is to override the initializer to have them set to
off by default as intended.

Spec for Pipe::Static's directory_listing:

- When directory_listing is off (default in Amber), response is 404
- When directory_listing is on, listing is allowed

- Specifying 'false' explicitly for option 'fallthrough' is not
  needed because the default false is now properly applied

Without this addition, any fonts processed by webpack got an URL
of /dist<font> and a "/" in between was missing.
