	Client

	Base Hud element for the mod's hud elements to derive from.
	Adds some kinda useless stuff, but mostly is there to
	take care of multiple gamemodes and any extraneous features
	that would otherwise require duplication.

	Also adds part of the ability to disable specific elements from
	the server side.

	Last Updated March 1, 2010
