[Live-demo] Wiki update for Git

[Siki Zoltan]

Dear All,

I would like to start the Hungarian translation of OSGeo Live 
documentation. I'm already on the contributors list.
I've forked the OSGeoLive-doc repo on GitHub and created the "hu" 
directory for the Hungarian translation and adde myself to the 
translators list, translated a short file (presentation.rst) and made a pull
request to test the workflow.
Is it the right way?

Zoltan
