More info on Makefile targets. Removed tabs to ensure that the file
looks ok when viewed in broken editors.
Noted the need for gcc for the depend targets.
Added some more info and various corrections. Unified the writing
style a bit (US text convention with two spaces after sentences seemed
to be predominant).
Added a snapshot target to export to Pike-vX.Y-snapshot-yyyymmdd.tar.gz
* Added instructions for getting pike from cvs.
* Added README-CVS.txt to the dists.
Updated the file to really be what it is supposed to be.
Suggestion from Leif Stenssion that I almost forgot about.
