Releases for Organic Groups Collections

Initial release of the Organic Group Collections module. Current known issues, since I don't have a known issues file:

1. After creating the first new pre-configured panel, you are redirected back to the front page instead of the Collections configuration page.
2. Many of the various configuration pages have titles that are, at best, erroneous, and at worst, downright misleading. I'm working on a more consistent and informative titling system.
3. There's a very preliminary system in place that creates a relationship between og panels that have been created via Collections and the original pre-configured panel from which they were spawned. In the future, this COULD grow into a system for performing mass operations on og panels that have already been instantiated; however, for the moment, the link is very weak. If you delete a pre-configured panel that's spawned og panels, that relationship will be forever lost, short of directly editing your database (NOT recommended for the faint of heart).
