Releases for OG Mailinglist

Correct attachment handling is missing, other than that it's usable.

Fix bug preventing email replies to a thread from sending out emails to the group.

Changes since 6.x-1.0-beta6:

Highlights of this release include a number of new hooks, a new module og_mailinglist_flag which provides integration with the Flag module to provide an easy way for members to toggle on or off their subscription to a particular thread.

Split out filter code into its own include file. Variety of small bug and documentation fixes. Ensure that non-utf8 text + subject lines are converted to utf-8. Handle emails better w/o subjects. Added module to provide integration with og_forum.

Yeah! The first beta.

The biggest change since last time is #782360: Replace the current Drush system for handling incoming mail with a mimemail-inspired POSTing system which makes it much much easier to install OG Mailinglist as well as integrate with different MTAs.

Whole lotta changes. See http://github.com/KyleAMathews/og_mailinglist/commits/master for a more granuler look at what's been happening.

High level overview of changes is:
a) spaces/purl dependence was removed
b) Can set default content type for new nodes from email
c) Improved thead detection for new comments
d) lots of small bug fixes.
