Sort user's games alphabetially
Add remove_game method to User

Removes the game from the user's collection if it's in there, and if
the game is not in anyone else's collection, removes it from the system
entirely.
Add destroy action to MyGamesController
Add a simple (not nice looking) implementation of remove buttons

I want to come up with an interface that works well on the desktop
and on mobile. The idea with this current interface was to hide the
remove buttons initially and then show them with a menu click, then
hide them again once the user clicked one of them and removed the
game they wanted to remove. Right now they're just shown all the time
and it looks really bad on mobile (the buttons go below the titles).
Look into using an icon font (X) icon instead of the text Remove and
make it not break to the line below on mobile.
Add FontAwesome
User can click Edit List to delete games

Replace delete buttons with (X) icons, hidden initially
Add 'Edit List' link to top nav bar. When the user clicks this
it shows the (X) icons by each game. Clicking those will delete
the associated game and refresh the list. When in edit mode the
'Edit List' link changes to 'Done Editing'. When the user clicks
that the (X) icons are hidden again.
