Use BuildID rather than rev in package version (#2210)
Use BuildID rather than rev in package version (#2210)

Since I switched to specifying the version of the VSTS build to match
the real build number, the `rev` portion of the ORIGINAL_BUILDVERSION
hasn't been increasing, because `01` is always available. Use BuildID
instead, which is guaranteed to be unique across a VSTS account.
