Fixed:
ratethisfest.appspot.com was not showing 'CHOOSE YOUR FEST' option and
showed a broken fest view composite instead

Added:
'CHOOSE YOUR FEST' screen has a small bit of info about ratethisfest

[Lollapaloozer]ViewComposite allows selection of year to view ratings
[Lollapaloozer]ViewComposite refactored dropdown event handlers

[Lollapaloozer]RateComposite GWT dialog button click event refactored out
of the main class
[Lollapaloozer]RateComposite properly redirects to Facebook/Twitter login
start if user is not logged in
