cvsfs 1.1.9 released

This bugfix release fix an error in cvsmnt which prevents the 'executable'-flag of files being presented when the default file mask (used when none given) applies. Also the default directory mask is no more hardcoded in cvsmnt.
Refactoring the communication to the CVS server to ease the implementation/use of new commands - no new user level function usable yet. Internally big steps done to support check-in and update which hopefully ready to be released next.
