"""
A note to anyone intending to work on this in the future... This dialog is
designed to be as stateless as possible. That is, all the information about
properties being changed, deleted, added, etc. should be kept in the SVN admin
system, not in this dialog. SVN should be keeping track of this info, not us!

To this effect, changes are applied immediately... no saving lists of changes to
apply later, no trying to keep track of what was done recursively and what
wasn't; just do the work and make sure the UI is sensible.
