GCI2012: Advanced Keyboard Configuration - Added "Controls" tab to settings, where you can set master game-wide controls. - Can revert master key bindings to game's default key bind. - Per-team binds now default to "Use my default", but you can override those binds if you want to. - New key binding interface. - Removed redundant second confirmation prompt for deleting a team. - Added "reset all binds" button to the binding interface in both the main settings and team settings. - I discovered that the reason keyboard camera controls were "broken" is because they were never implemented! But don't worry - I took care of that for you, too. :) (this also closes bug #120)
