* Update year

* Add handler of */* requested response

* Change behaviour of responders

* Add some responders tests and change behaviour of type selector

* Add responder invalid extension test with */*

* Make valid? return false on missing field

Calling params.valid? now returns false regardless whether the cause for
failed validation is a field missing or field's value not passing
validation.

Previously, only field's value not passing validation was returning
false, while a missing value was (incorrectly) raising an exception.

Tests are also fixed to behave as it was intended.

* Avoid raise_on_error as suggested by @eliasjpr

* Rename extensions

- Rename Amber::Extensions::<Type>Extension into Amber::Extensions::Type
  (This makes it uniform with other things in Amber, e.g. pipes are named
   Amber::Pipe::<Name>, not Amber::Pipe::<Name>Pipe.)
- Rename files accordingly as well
- Add test for HTTP extensions

* Change test name

* Use Digital Ocean's 1gb machine. 512mb is obsolete.

* Remove unconditional search for real client IP (#534)

* Pipe::ClientIp - saves client IP to Amber context

- Add Amber::Pipe::ClientIp
- It looks into configured header names (default: "X-Forwarded-For"),
  finds the first header that exists, and takes its last value
- Saves the value into context.client_ip as Socket::IPAddress(addr, 0)

- Covered by specs

- Along the way, sort in alphabetic order methods on the controller
  that are delegated to context for easier lookup and modification

* Add ClientIp pipe template to config/routes.cr

- Add Amber::Pipe::ClientIp to template config/routes.cr
- By default, add it in disabled state
- Even though ClientIp has default header ("X-Forward-For"), do mention
  name explicitly in the template, and also show an array to be as
  easy and intuitive as possible for users to understand what the header
  name is and that multiple headers are accepted

* Use first instead of last IP address (#564)

* Make non-matched header name more obvious (#564)

* Improvements as per discussion #564

- Fix/improve examples

* Capitalize message

- Add migration directory to IndexError

- Add test to confirm

* Move "X-Powered-By: Amber" header to its own pipe

* Make test route unique

* Remove unnecessary comment

- The module name is Validators not Validations

* Ability to configure 'cors' pipe at initialization (#171)

Specs are included.

* Make Pipeline's "valve" configurable at initialize (#171)

This does not appear strictly necessary, but does not
have adverse effects.

* Minor, fix spacing

* Improve CORS pipe (#171, #540)

* Improve CORS pipe 2 (#171, #540)

- Moves the session store into router/session as this is where is
expected to be

The pipe name now matches the filename in which it is defined. Also,
it no longer implies that it is the last one in the pipeline.
