Subject: When you delete something in /cloud stay in the right folder.

When you deleted a file in /cloud you was always jumped back to /cloud/[channel],
now you will stay in the parent folder.
Some more doxygen documentation.
Removed duplicate data from logging output and reduced logging in RedDAV in general.
