initial stab at packaging using ship_it

So this is not yet ready to merge.  The good news is that I'm able to make an RPM with this changeset which seems to install properly.  The bad news is that now that we've changed Sideboard to use a single virtualenv, we are no longer able to bundle plugin Python dependencies with those plugins as easily :/

So basically, we need to be able to have packages somehow insert their dependencies into Sideboard's virtualenv on install.  We do NOT want to pull down from the internet when we do this.  Perhaps the solution is to include the packages and then do the equivalent of ``python setup.py install`` on each of them to make sure they're installed, but I'll need to give that some thought.
This is the file I developed for my current project, and it seems to work great.  I'm loving ``fpm`` and although I've only tested with RPMs so far this works great.  I do need to add some smartness about uninstalls, but we can do that down the road and to me that's less of a concern than the install.
