the version being reverted to is created. This clone has the previous head version
as its ancestor and a wcm:reverted aspect applied. wcm:reverted contains
wcm:revertedid, the node id that the reversion is a clone of. Revert to version is
now a simple call to a new AVMService method, revert().
Propagated this to the remote API.
Modified the the AVMRevertToVersionAction to use this mechanism. Though really the
action isn't really needed now.
