[CM] cm-gtk package available

[Rick Taube]

Ive released the CM interface code (Plotter and CMIO) as a "breakout 
package" that you load by doing
	(use-system :cm-gtk)
the good news is that you do not have to do any configuring in SBCL or 
OpenMCL anymore, the package should just compile/load out of the box in 
these lisps:
	sbcl 0.7.9 or higher  (linux)
	cmucl 19b or higher (linux)
	openmcl 1.0
