By default, mod_evasive creates a file in /tmp for every blocked client,
with a name like dos-<IP address>. I didn't know this was going on, and
found 1,659 such files on the facilitator dating back to May 2013. The
contents of each file is just a PID, I think.

This configuration option prevents the creation of such files. Blocked
IP addresses still turn up, however, in the error.log that is not
disabled, in lines that look like
	[DATE] [error] [client X.X.X.X] client denied by server configuration: /usr/local/bin/facilitator.cgi

You can't just tell setuptools not to download things, so instead set
the http_proxy and https_proxy environment variables to point to a
local port.

- this allows things to work easily even on pre-installed system images, such as liveCDs, c.f. debian bug #594175

Death-on-any-error was meant as a failsafe, to prevent runaway behavior
like repeatedly connecting to a facilitator that is down for some
reason. It turns out that long-term proxies like Cupcake want to keep
connecting after a temporary loss of connectivity.

die was intended to prevent future network operations. In reality, it
just changed the color of the badge and waited for the next polling
interval.

- To support multiple authenticated bridges, we will need to fix #10196 and #11574

facilitator              -> fp-facilitator
facilitator.cgi          -> fp-registrar.cgi
facilitator-email-poller -> fp-registrar-email
facilitator-reg          -> fp-reg-decrypt
facilitator-reg-daemon   -> fp-reg-decryptd

This way you don't have to maintain access to the phone number used when
you registered.

I think I left these in because the host I was running the exercise
script on had an old tor, but they're not needed anymore. Cf.
4f7b24b3.

Use argparse instead of getopt and factor out much duplicate code.
