Transfer mongoid-enum to github.com/mongoid?

[dblock]

I had https://github.com/mongoid kindly donated to the community by the nice folks at MongoDB. The three people who have org level admin access are currently @durran, @estolfo and myself.

I want to invite this project to be moved to the org. I think it makes good sense to group mongoid projects together and have continuous support from MongoDB, the company, over the long term. All admins of this project will continue having admin access of course, but this would reduce the bus factor since currently only @thetron can add maintainers here.

If you think it's a good idea, please transfer this project to me and I'll move it into the org and please add dblock@dblock.org, emily@mongodb.com and durran@gmail.com to rubygems.
