[Owncloud] ownCloud 3 bugfix release

[Frank Karlitschek]

Hi,

we should do a ownCloud 3 bugfix release as we did with ownCloud 2.
We already have a few important bugfixes and also small security related changes.

The idea is to cherrypick the changes and port it into the stable branch.
Please be super sure to pick only stuff that´s well tested and doesn´t break other stuff in ownCloud.

The plan is to release the 3.0.1 bugfix release on March 22. or 23.

I hope that works for everybody :-)

Cheers
Frank
