GameUI refactor (part 7/7): Finish to include profiler things to GameUI

Other changes:
* Add GameUI clarification comment
* Move force_fog_off & disable_camera_update flags from GameUI to Game, it's not UI related
* Properly init GameUI::Flags
* Move toggleChat toggleHud & toggleProfiler to GameUI
* Add gameui.cpp to LINT whitelist
