Contacts: Check that UIDs really are unique on import. Better solution would be to suggest to merge contacts, but that will have to wait to OC5 ;-)

Applied patches by Nicolas progweb at free.fr - https://mail.kde.org/pipermail/owncloud/2012-April/002900.html

wrote a new versioning app over the weekend. Basic functionality to far but it works (TM) and has all the needed features (TM) for ownCloud 4. Userinterface integration and small improvements still missing.

first step to an public api of ownCloud for the apps. In the future they shouldn´t call internall classes, functions or session variables because this will change and break in upcoming versions. Apps should only call this public interface that we will kepp stable over different releases. The namespace is OCP for ownCloud public. This is just the first step. more coming soon

- Added overlay toolbar to contact photo with 'Delete current', 'Edit current', 'Load from OC_Filesystem' and 'Upload' options.
- Made action icons translucent instead of hiding them.

Personal settings: Emphasized labels etc, mono-spaced generated paths and moved text formatting to style sheet.
