fix kolabd crashing on startup

[Michael]

Hi,

I'm using Kolab 3.1 from:
deb-src http://obs.kolabsys.com:82/Kolab:/3.1/Debian_7.0/ ./
deb-src http://obs.kolabsys.com:82/Kolab:/3.1:/Updates/Debian_7.0/ ./
Build date: 11-Nov-2013

kolabd/kolab-server is crashing if there's no dirsrv/389 online.
For me that's the case nearly at every system-boot because kolabd apparently 
starts faster than 389 can initialise. 

Maybe there are better places to fix this, but I've added the following to
/usr/lib/python2.7/dist-packages/kolabd/__init__.py:

With this it works for me, kolabd waits for dirsrv to startup.

Sorry for not using pull requests as Timotheus and Torsten suggested.
I haven't played with pull requests yet. Would it be possible 
here too or only in case of fixes for the documentation?
