[RFE] uuid needed as an automatic property

To track files moving we desperately need to have a uuid or equivalent
assigned to each object placed into the repository perhaps as a property
called svn:uuid (suggestion).

Case in point, tracking file movement isn't pretty but it can be managed by
checking the uuid of the deleted object against the uuid of added objects in
a post/pre-commit hook. I know other work is going on in this area, but
this would be a step in the right direction.

As a side note, It would be interesting to see, if we could query the
repository to see where a file identified by a uuid is currently residing or
last resided.
