While in Agde, at OBM developpers summit, I did the first steps of technical integration of MiniG with OBM :
* Private & public contacts from OBM are visible as contact groups, used for email address autocompletion
* Email address gathering : recipients of emails sent through MiniG are automatically added as private contacts in OBM. They will be available for autocompletion next time the MiniG composer is used.
* OBM user settings are pushed to the MiniG ui, to avoid redundent preferences (language, timezone, etc)
