Made revert to version behave better. Now when a node is reverted a clone of

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.
