This should fix the symptoms of the problem we've been having where a
few API clients using the MIT Zephyr mirroring system sometimes seem
to end up with a too-old value of last.

This change adds a copyright notice and moves our site-specific bits

I would prefer to be testing the attribute itself rather than the
version, but it's not easy to access without an actual request object,
and I'd prefer to compute this once-and-for-all on startup, rather
than on each request, since the latter just seems fragile.

This adds two characters to the length of our default format field, but
based on a conversation I had with kcr, I think this should probably be
okay. If it's a problem, the symptom we'll see is that certain people
will be unable to send zephyrs with this default format (so, certain
Humbug users will have their forwarding consistently fail).
We need to remember to, in a future commit (once everyone has started
using the updated version), remove the:
> or notice.format.endswith("@(@color(blue))")

Fixes#602.
I replaced the SIGKILL with a SIGINT, and then catch SIGINT with a
handler. This handler calls cancelSubs if necessary, and can later be
edited to perform other clean-up operations, too. I thought about, in
this same commit, changing the SIGTERM in
maybe_restart_mirroring_script to a SIGINT, but after tracing out the
code paths, I realized that isn't necessary. (The SIGTERM is
necessarily performed on a process that has not subscribed to any
zephyr classes, so cancelSubs is unnecessary. If we do think that we
may want to add additional clean-up operations in the future, though,
then it might be worth investigating changing this SIGTERM.)

Bots are not part of what we distribute, so put them in the repo root.
We also updated some of the bots to use relative path names.

My previous commit (fbdc092029bbafea716e27fbb99fec58a6f24392)
incorrectly specified that you must have a version of python-requests
greater than 0.12.1, when it should be a >= relation since 0.12.1 is
sufficient.

Previously, if users of our code put the API folder in their pyshared
they would have to import it as "humbug.humbug". By moving Humbug's API
into a directory named "humbug" and moving the API into __init__, you
can just "import humbug".

The old-style api.humbug is deprecated, so we rewrite the path for things

This was causing about 10% of the time, personals being forwarded by
tabbott/extra@ATHENA.MIT.EDU to get this error:
zwrite: Field too long for buffer while sending notice to

We don't fully understand the cause of the problem, but this fixes it.

Sometimes the very first message we send isn't received by
python-zephyr; this could be because of our growing a 17-message queue
of zephyrs to service, so let's not do that.

This ensures that Humbug receives the verbatim text of the Nagios
body, rather than a slightly modified version. Tested by running
manually.

The refactoring that we did a couple weeks ago to make the zephyr
mirror script restart itself automatically (by splitting it into
zephyr_mirror.py and zephyr_mirror_backend.py) had a poor interaction
with our code for killing old zephyr_mirror processes (to prevent
double-mirroring). If you manually ran two copies of the outer
mirroring script (zephyr_mirror.py), then the second one would on
startup kill the first one's zephyr_mirror_backend.py children (for
being duplicate zephyr_mirror_backend.py processes that would result
in double-mirroring). However, importantly, it did not kill the first
mirroring script's zephyr_mirror.py parent process, so the first
mirroring script would then proceed to startup up new children. The
process then repeats, with the two scripts' roles reversed.
This issue didn't affect the sharded mirroring case, where I had been
doing the testing of the kill code with that refactoring, because we
don't have a version of the outer zephyr_mirror.py loop for that
situation (a consequence of it being hard to restart the threads
properly with the run_parallel API that we're using to spawn all the
children).

This is probably a lot more annoying to use, in that e.g. there are
separate log files for the two directions of the mirror, but we
haven't used these logs for much, so whatever.
