Wuala (Oberstrass)

* continuous backup on Windows: newly created backup folders can be backed up on every change (like sync)
* new import for contacts: Our contacts import library was not maintained anymore. We have replaced the failing contacts import with our own implementation. currently we support GMail & Yahoo
* improved accessibility: support for large fonts and high contrast color schemes
* early access release of a new technology for Wuala Drive (to replace Dokan): start Wuala with "-useCBFS" parameter to try it out.
