Hexworking

I noticed that two migrations (20130108004513_create_boards.rb and 20130108004513_create_games.rb) had the same timestamp, which was confusing rake.

I just changed 20130108004513_create_games.rb to 2013010800451**4**_create_games.rb to fix the conflict.

Also: Cleaned up root routing, moved hexagons.js to app/javascripts/, now loading hexagons.js using Jquery's ready() to make sure DOM elements (like our canvas) are loaded first.
