Move wac to txwac
First round of twistifying the code
Shockingly, lots of parts work.
Just don't even think about trying to use pagination.
Made current, next, previous, and all work
Fixed more pagination, PEP8
Removed things that will never work (e.g. __len__ that return deferreds)
* Fixed _slice and __getitem__ on pagination items
Updated info, removed travix / tox (for now)
