added: now we have a fourth part in permissions (guests)

e.g.: 07555 means:
           7 for owner
           5 for group
           5 for others
           5 for guests (not logged users)
added:     the sticky bit for directories
           e.g. permissions to a directory with a sticky bit set
           can be set to: 017555
rewritten: rm/mv winix functions to correctly understand the sticky bit
added:     Dir::FollowLink() recognizes ".." and "." now
           consequently System::FollowAllLinks recognizes it too
added:     umask -- calculating privileges for new files/directories
           all users have their own umask (in meta)
           and there is one in the config
           (for guests and when a user has not definied its own one)
removed:   mount option: only_root_remove
