bip: move the BIP relay into pySim.bip
Move the code from pySim-smpp2sim.py to its own file, so it can be properly extended. The current file parses argv, opens a reader and starts the Twisted reactor at import time, so nothing else can import it. No functional changes yet, improvements follow in later commits.
