[Unifighter-cvs-commits] code update

[Dan <mrb...@to...>]

I've added the new UniTimer source and header files. I have also
updated event_handler and main to initialise / update the UniTimer.

Added UNI_Character and its abstract baseclass UNI_Entity.
Updated Game class to use UNI_Character.

Updated Global.h to give project-wide access to the UniTimer class.
