Updated hash syntax
Use '' when not interpolating
Added thin to the Gemfile
Stripped trailing whitespace
Ran `bundle`
Changed some spelling
I'm not even sure how that worked before...
Moved some whitespace for readability
Actual exist check for names
Using Sinatra's actual methods for errors
Better in an if..else than unless for token checking
Merge branch 'feature/cleanup' into develop
