This allows you to use `store: :signed_key` and `expires: 0` in the
environment.yml file.

* use secret_key_base instead of generating a key on restart

* modify tests to match

* fix template for session store

* PR feedback

* formatting

Application controller was not being loaded in the correct order when using
`require "./src/controller/*"`.

To correct the error loaded application_controller first. Also did a little formatting for 
readability

The MIME media type for JSON text is application/json. The default encoding is UTF-8. (Source: RFC 4627).

Currently checking content_type with == will not match content type formats for `application/json;charset=UTF-8`

With this change the check for content type application/json should be correct.

* fix method signature to match Channel

* fix others as well

When defining a socket endpoint it withing route it currently
throws an error socket_endpoint method is not defined. This is due to
the fact that the socket_endpoint is not accessible through the routes

In order to correct the bug a websocket method was defined in place of
socket_endpoint in DSL::Router

Changes:

- Adds websocket as a  method instead of macro to Router DSL (See #224)
- Adds specs to ensure socket endpoint are defined
- Removes socker_endpoint from Amber::Server
- Makes socket_routes public

This changes the current API from socket_endpoint to websocket since
this naming was to honor proposed changes in
https://github.com/amber-crystal/amber/pull/224
