Eliminate the loopback that has been causing so much trouble.

`localhost`, `0.0.0.0`, `127.0.0.1` each works only in some places some of the time, this works around the problem by overriding Yajsml's built-in request mechanism in favor of a hacked together one. TODO: Serve files from another service, or directly from the file system in order to make this unnecessary.

Fixes #747
