Always build docs...

Forgot that I never finished this, and then realized that my github repo was not a direct fork of the testapp repo.  So I set it up correctly on github (I hope).  Then simply removed the if check from the doc build in post_receive.py, and also the else, since we're always doing it.  I think the only way to test this is to put it up on webfaction and make sure it works, short of the very involved process of setting up a  testapp locally?
