IM with OMEMO support

[Jan Kokemüller]

Hi Chris,
I'm using Gajim with the OMEMO plugin successfully on FreeBSD. I didn't 
build the plugin manually, however. I've installed it through the plugin 
manager of Gajim. Shouldn't that work on other OSs, as well?

I think I had to install one more package that was a runtime dependency 
of the OMEMO plugin. There was a log message about that in the standard 
output.

Cheers,
Jan
