Stale branches to be delted

[aramprice]

The following branches are years old and appear to be related to feature implementation. Many of the contributors to these branches are no longer active in the community.

I have prefixed a bunch of suspected dead branches with TO_DELETE-, list below. I propose these be deleted from github:
