Config plugins are generally broken and not very helpful about it

[KristianLyng]

I'm sure the build is broken due to my work, but the bigger problem here is that it's a nightmare to track down what's actually happening (or not) as far as configuration goes. I was building compiz without core.xml and didn't even get a hint about it, for instance. Ini just .... fails.... CCP does nothing.... No errors, nothing. As far as I can tell, everything else is working in my setup.

This needs a major overhaul. When things don't work, people should be told WHY. Compiz is way too content with letting things silently fail.

My current idea/plan right now is to make a new super-simple config plugin and add error handling to core while I'm doing that. The plugin is not the crucial part of that task, the core improvements are.
