A few new things:

A few new things:

	. The interface part:
			. created intf_AssignKey, intf_getKey and intf_AssignNormalKeys
			these new function are a first abstraction of the the key handling system.			It makes use of a new structure in the interface : p_keys.

			. AssignNormalKeys is commonly used in all the interface plugins.
			AssignKey is used to allow the SDL interface to react nicely.

			. Now the plugin struct element psz_filename is filled (and freed
				at the end of the program).

	. the SDL plugin:
			works but does only display a green screen for now. so don't use it !

	. Please try and compile the client on your box with this version.
		I've tried a few output plugin but not all.
