Converted to module sinatra app, organized files into directories
Started adding integration tests on the auth routes
Removed facebook support

DoodleMonster will use native facebook support provided by appMobi, so
we don't need the server to make any calls to the facebook api anymore.
Refactored auth integration tests to make them more readable and use better practices
Extracted email authentication application service from /auth/:email
Introduced PlayerService application service
Moved EmailAuthenticationService into the SevereSunset::Application module
Added tests for new player validation and moved the validation into the new player application service
Create route POST /players to replace POST /createacct

The route /players is more RESTful. Also moved the tests into a new
player_specs test file.
No need to store the uri as a property of Player
Commit a couple of TODOs
some intelliJ config
