New repository for unofficial packages

[J. A. Calvo]

Hi Zentyal community,

This is to introduce our new PPA for non-official or unmaintained packages:

https://launchpad.net/~zentyal/+archive/2.0-contrib/+packages

As you can see, egroupware is the first and currently only package there. As you may remember, we dropped its official support in favor of the new zarafa module and now it has been removed from our main repository.

The Installation Guide has been updated to reflect the new instructions to install the old ebox-egroupware package.

We also want to announce that if you want to contribute by developing any new module we will be very glad to publish it in this new contrib repository to make it easily available to the rest of the community. You can find more in our How to Contribute section.
