OBM technical integration

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)

New minig release

Just released new MiniG backend & frontend binaries on minig.org. Also made an announcement on freshmeat to grab new users/testers.

This new release features folder tree, instant unread count updates, html email cleanups to strip images & javascript and my new imap4r1 library.
