A wrapper around AVMService which knows aboout locking. It works
by auto-locking on write operations or throwing an AVMLockingException
if the requested target is already locked to another user or to a
different store in a web project.
It is wired up as avmLockingAwareService, AVMLockingAwareService, and
indexingAVMLockingAwareService. It isn't hooked into anything
else yet.
