Investigate moving from JSON/YAML parsing to ConfigObj

[winhamwr]

ConfigObj would allow us to mostly get out of the low-level validation-parsing game. It has built in validation and template expansion. It uses python templating instead of Jinja2, but it's not clear if that's much worse. It would also certainly be possible to add Jinja2 support.

Need to evaluate how well the current functionality would fit our needs and how much of a risk the current project status is. Looks like there are quite a few open issues and the project hasn't had any commits since 2011. I would much rather contribute to a shared library than re-implement some of the functionality inside Neckbeard though.
