Jetpack 2.9.1 Beta 1

Very minor changes in this point release. The first will only affect users who were using our last beta version kinda early on -- one of the features we were testing had its option commented out, but functionality was never disabled. This fixes that.

The other option is a JS glitch that can prevent the saving of posts if you're using After the Deadline on your user profile.

Short beta, release soon.
