Gamemode Switcher
New F3 debug feature which allows you to switch game modes with traditional "tabbing" functionality.

Hold F3 and tap F4 to open the menu. Tapping F4 will cycle the game mode, or you can use the mouse. Release F3 to apply. Your last game mode is remembered and will be the first selected option, so you can quickly toggle between two game modes with a single press of F3 + F4!
