improve RevertableProperty combining
* Various property combinators that combined a RevertableProperty
with a non-revertable property used to yield a RevertableProperty.
This was a bug, because the combined property could not be fully
reverted in many cases. Fixed by making the combined property
instead be a Property HasInfo.
* combineWith now takes an addional parameter to control how revert
actions are combined (API change).
