[proposal] move cforms in core

[Stefano Mazzocchi]

The more I go around talking about what cocoon is, the more I think that 
cforms should not be a block. This also requires the 'template' system 
to reside in the core.

So, here is my proposal:
 1) move cforms in core
 2) stop considered 'alpha' and decide to release it when cocoon 2.2 is 
ready (how far are we from stabilizing cforms anyway?)
 3) rename jxtemplate as CTemplate and moving it in the core as well

Comments?
