GCI2012: Autoupdate Button in Settings

cmake verbosity/documentation/cleanup/formatting

Implement some more callbacks

Delete poller when game is over

less linking needed, raise minimum_osx_version when videorec is enabled

Merge with default

hides the 'email' prompt on the feedback page (as that doesn't work, so it's a misleading/useless feature), makes the "please add your email" text a little nicer and more noticeable, and makes the "feedback" and "downloadable content" buttons on the main menu a little bit larger, and more clickable.

Some fixes
