Remote sound works fine these days. If people want to turn the
preference off, they probably want to do it in all cases, and can
'customize before install' to alter the rest.
This unfortunately has a decent amount of fallout: add a wrapper class
in config.py that reduces much of the churn.
Another big piece is that gsettings can't accept arbitrary paths like
gconf would, everything needs to be described in the schema.
Also do a bunch more RPM spec modernizing
Despite being a known quantity, autotools is so overkill for our needs,
so let's drop it and replace it with a much simpler and easy to customize
system.
