Adding a new protocol

[Eduardo]

> What protocol were you thinking of writing for?

I'm using the yowsup library, with a python client whose only task is to 
forward the messages to Telegram. My idea is to connect pidgin with that 
script,  via a shallow plugin doing IPC, for example, or by presenting 
the yowsup client as a server to pidgin (using a basic protocol).

Hope that makes sense...

Thanks a lot Eion! It's exactly what I was looking for. You'll probably 
hear from me again if I can get something working ;).

Cheers, Eduardo.
