In Firefox, the search field was so large that it jutted below the black bar it sits in. This has no effect on the size in Safari and Chrome. In Firefox, the search field would look even better at 15px, but 15px bumps the field down too small in Safari and Chrome.
This reverts commit 972aac6. This prevented tests from being run.
Add 403 handling to expire current session and show 403. This fixes a small bug: if someone is logged in and changes the application oauth settings then they would see an octobouncer cat with no message or help as to what was happening. This bug also appeared if the user revoked access to play and wanted to readd it. Added 403.html to public and styling for it and also iphone version. Nothing fancy. Steal Octobouncer for our own gains.
