Rework debugging info - Githubissues

Few things should be accessable without enabling debug mode:

Pressing F3 at any time shows the game version on the top left and FPS counter on the top right.
You can enable or disable FPS counter by pressing F key, no matter whether the detailed F3 info is enabled or disabled.
Frame counter should be toggleable by pressing CTRL+F, and it shown below FPS counter.
Mute function should be accessible any time by pressing M button, and the text 'MUTED' will be displayed on the bottom-right.
