Fixes for a RoR app

1) The website is in German when viewed in IE. Please change it to EN_US. 2) On [login to view URL], the times are still in international format (18:00 instead of 6:00 PM). Please make it so it says AM and PM 3) Remove the map from the event pages 4) The event pages say "admin submitted this event on {{date}}" instead of "admin submitted this event on 11/27/2011" 5) The avatar upload on [login to view URL] doesn't work. It uploads the photo but is not called correctly on profile pages. In addition to those changes, an update of Ruby and MySQL are needed.
