Beta v124.0.2-aero

Aero should be fully fixed, the UI is on the same level as 115 ESR with a few adjustments.

1: Native elements are brought back and enabled by default. If you do not like them, set widget.non-native-theme.enabled to false.

2: Windows 7 Aero fog is halved in intensity. Now you can see stuff behind the r3dfox window, while also being able to read it with dark backgrounds.

3: Windows 8 item colors are black now so tab text and things don't become unreadable when the window is inactive.

Haven't tested on XP/Vista (extended kernel) nor have I stability tested.

Let me know what bugs or issues you encounter with it.
