Patch for mercurial support...

[Brian Kosick]

Hi All,

First off, I'd like to say that I'm still in the n00b period of learning
python and have heard that bad coding with it takes a little bit of
extra effort.  I'm happy to say that I think that the koji maintainers
are too lazy to put that extra bit of effort in.   I found the code in
kojid to be easily readable.  The variables, classes and methods were
well named and the flow of the code made sense.

What are you guys thinking?!?!

These are tough times and you should be thinking about naming schemes
that only the original author could love.  Cryptic variable names and
convoluted work-flows are core synergies to job security!

Anyways, in between trying to deepen the dent on my desk via the manual
"forehead" method, constant interruptions, and managements infuriating
refusal to allow me to throttle those same interrupters, I came up with
this patch to koji 1.2.6 it allows Mercurial to be used as a SCM.

Thanks for the un-convoluted code!

Brian
