Slave backward compatibility totally broken and underdocumented

[dabrahams]

I just upgraded my buildbot and found my slave didn't work. On #buildbot they tell me there's a whole new package, buildbot-slave. So I installed that, but then the existing buildbot.tac in the slave's config was using methods that don't exist anymore (or have moved), etc. Strongly suggest you find a way to preserve the interfaces used by legacy buildbot.tac. No instructions for upgrading slaves in http://buildbot.net/buildbot/docs/current/. When I go to the manual, the section on installing only barely hints that I might need to find a different package. The PyPI page makes no mention of the other package ( http://pypi.python.org/pypi/buildbot). To find the real instructions I have to click the obscure "more..." link at http://buildbot.net/trac.

There are better docs, but the automatic upload of new docs seems to be broken.. I'll try to fix that.

OK, here they are:

among other changes.
