[dev] Restructuring the Kolab module

[Chuck Hagenbuch]

Quoting Gunnar Wrobel <wrobel at pardus.de>:

> The new structure I added during the last two weeks is something that
> I believe we will be able to keep stable for the next few years. It
> actually maps to the underlying concepts of the Kolab server. The
> broken approach I added with my original share driver did not.
>
> I added a lot of unit testing which caught many initial problems and
> real world testing seemed rather robust now. So I commited the switch
> to the new module structures.

Sounds great. :)
