started adding warcprox
Merge remote-tracking branch 'jack/dev.warc_server' into jack_warc

I need the PyWB intigration
PyWB added
added warcprox to .gitmodules
removed warcprox from library and added warcprox task
warcprox + phantom intigration are buggy but working. I have not really looked at playback yet, but it needs some work.  TODO's 1. cert handling  2. proxy socket error handling 3. more robust proxy teardown 4. Task managment needs a lot of work.
playback is working
working prototype
This is a working prototype of Perma with warc record/playback. Requieres warcprox which can be installed with pip
