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
