Get privacy

Hi again,

This should fix the "known issue: The privacy status is not retained..."
First I have [fixed the API](https://github.com/cweiske/SemanticScuttle/pull/6), which has not been merged yet, but it hopefully will.
This modification will use the new API information only if available. Otherwise it will behave like previously.

I've set up a testaccount on my installation of semantic scuttle which uses the modified API. You can login to try it you:
server: http://fave.ihdg.ch
username: testUser
password: 'same as username'

Currently the status is just shown as text. Maybe an icon would be nicer.

Here some screenshots
