Ralf Becker 8f7f89666f New options for filesystme stream-wrapper:
- all:   false (default) = ignore files starting with a dot '.',
  true = show all files (. and .. are always ignored!)
- exec: false (default) = do NOT allow to upload or modify scripts, 
  true = allow it (if docroot is mounted, this allows to run scripts!)
--> deny_script method was added to egw_vfs and calls to it from
filemanager
Other fixes:
- missing write rights of the webserver were not removed from perms
  (causing warnings to be displayed in the ui)
- rename was not working due to typos
--> should be backported for obvious reasons to 1.6
