LDAP: identify (map) users with their directory UUID. Fixes the issue, that usernames for owncloud will change, when the DN changes (which happens rarely, but it happens).

Fixes a bug where if one tries to delete a file, then clicks undo, and then tries to delete the file again, no questions or undo options were presented.

Essentially, just set FileLists.lastAction = null when one clicks undo.

LDAP: permanantly watch group members. Emit post_addToGroup resp. post_removeFromGroup on membership changes, so that Sharing App can take care of files shared within the groups. Requires and relies on background jobs.

You have to put a presentation file that contains the presentation defined in html into your ownCloud with the file extension .impress
Then you can use this app to play it. It also contains a demo presentation that you can use to learn.
Help is welcome to improve this app. :-)
