Reset version number to 2.0.0-SNAPSHOT
Reset version number to 2.0.0-SNAPSHOT

Reset dependency versions to SNAPSHOT versions.

Usually, after a release we would increment the version number (e.g.,
after release 2.0.0 we would go to 2.0.1-SNAPSHOT) but for the betas, we
return to 2.0.0-SNAPSHOT again.

This used to be revision r5393.
