Also configures Bitmessage so that message recipients whose address labels contain <> enclosed
email addresses are automatically sent anonymous notifications through mixmaster which say:
"someone is trying to communicate with you on a safer channel" (subj: "spidey sense")
Instructions: Boot the Tails operating system and enable persistence, then reboot, run this script, and reboot again.
Warning: Do not run this script if you already have Bitmessage installed in ~/Persistent/PyBitmessage.
Warning: We won't overwrite an existing keys.dat, but remember this script is not for reinstallation/upgrading/overwriting!
