mongoDB : v2.0.6 released

Bug fix release, it is now available in portage. Starting from this package version I introduced a logrotate script which compresses daily the mongodb logs and keeps them for a year.

Release highlights :

• mongos does not send reads to secondaries after replica restart when using keyFiles
• If only slaveDelay'd nodes are available, use them
• OplogReader has no socket timeout
