Release 0.9

I'm about to write some changes for omniauth, so I thought it best we first release 0.9.  Personally, I am using Lift 2.5.1.  Let me know what I need to do to help release the cross Lift versions, as I know that isn't automatic.

BTW, I also added my blog post on Dropbox in Lift at the bottom of the readme which some may find helpful.
