openhab - binding for the Bticino / LeGrand domotica system

Hello Kai,
As I mailed you yesterday, this is the binding for the bticino / legrand system.
My items sitemap and config are included as an example.
After this is merged, I would like to add documentation on how to use it and 
the current features / limitations.
Greetings,
Tom De Vlaminck (devlaminck.tom@gmail.com)
please move this code to openhab_default.cfg
