CVS redone

I just redid the CVS stuff, with a module named 'perlbot'. I imported the current 1.2.1 code, and tagged it as perlbot_1_2_1 . Please ignore the perlbot-1.2.1 module, and I'll try to get it deleted. Development will now use CVS, so fixes should become available to users much more quickly now.

In fact, in the future I hope to set things up so that you can just do 'cvs update' in your perlbot dir and you have the newest stuff. That will require that files that you want to keep between versions, like config files, be renamed in CVS so the CVS versions don't overwrite your copy... Or would CVS automatically handle such issues? Post to the forums or something if you can tell me.
