https ggate working tree

This is a working tree for ggate work.

This is a variant of ggatec using http(s) GET/PUT instead of talking to ggated.

Note that when I started on this project, that this would be completely standards complaint. After running into an issue w/ the wsgidav server not supporting partial PUTs, I did some research, and came across this post that talks about how the IETF intentionally broke partial PUTs, despite having the same problems w/ other parts of their spec.

Servers known to work:

• apache 2.2.x: can truncate file under some conditions

Services known to not work:

• wsgidav (Python): Does not implement partial PUT
