First pass at a script to dig through .git/objects and find dangling
tags. It likely has a lot of weird limitations, I don't know if it
will work with packs, and the policy it implments is pretty stupid,
but it is a sane start and should keep people from needing to
rsync anything except the .git/objects part of the tree.
The current policy is if a tag's gpg signature can be verified
and if the tag name does not conflict with an existing tag
place it in .git/refs/tags/. So far this only works with
dangling tags so I don't know if these tags will even be pulled
with the pack methods. But since we aren't quite going at
full speed on those yet we should be good.
