Switch to compass + sass for stylesheet
Update Padrino and few other gems
Update jQuery
Add new gem for capybara, integrate it
Add sass button dependency
Refactor MenuCategory::matching and Random controller

Change Random controller to use GET instead of POST for better UX

Change MenuCategory::matching to return a hash where the keys are the names
(from the arguments) that were successfully matched to a an existing
MenuCategory

Add amount and category tracking functionality to Random controller so
that the user can generate another meal without having to resubmit
criteria
Add styling, refactor views for styling and into a couple of partials,
update home pages spec for view changes and for case where user wants
to generate another meal with same criteria from before
Refactor footer style, add error pages, and prepare for deployment.

Remove Compass sticky footer, since it forces user to scroll down to
see footer even when there is very little content (ie. error pages)
Correct issue where footer area would shrink in size when browser window
was made smaller (even though footer text would stay the same size)

Add simple error pages, remove some debug code, and remove the stock
padrino favicon
