Features

[StenAL]

This PR adds the following features:

• The game is now painted in the center of the applet. Now, resizing the applet actually does something as the content is painted in the middle of it and IMO looks better. Since the game now utilizes space better, I also increased the default window size to 1280x720p.

Before	After

• Game audio can now be muted from the lobby selection screen. This is useful when playing multiple games on the same host to have audio only played once. To fit this on the home screen, I shifted the graphics settings up by a bit.
