Siamashka (thanks). It was adapted from the SVN Diff plugin.
Currently it supports SVN, CVS and GIT.
Fixed GTK warnings when the current file has no filename and when
the current directory has no version control system.
Made some refactoring changes to make the VC_RECORD struct contain
all necessary attributes about each version control system.
