it´s evil and deprecated

added a serverProtocol function that correctly returns the used protocol even if the ssl connection is terminated at a reverse_proxy or at a load balancer

i don´t understand why this worked before.

Applied fix from kalassico for "Chiper text must be a string" bug (http://forum.owncloud.org/viewtopic.php?f=3&t=2586&p=5094)

The data supplied is never used in OwnCloud. Removed the call from all the apps, and made the public API function empty.
