Update everything to 2.0 stable.

Matt, you didn't update many projects to the stable build. The only things that broke were my profiler hook (typo corrected in the API) as well as ILMerge on the DBUtil project:

error MSB3073: The command ""C:\<snip>\ravendb.contrib\src\.ilmerge\ilmerge.exe" /v4 /out:bin\Debug\RavenDBUtil.exe "obj\Debug\RavenDBUtil.exe" " exited with code 1.

That one I can't fix. Or actually, don't know how.
