Drop configobj dependency

[kernc]

Since our need for config parsing is minimal, and if we drop the only section in our config file (and make the keys global), everything can be covered in a few lines of code, hence the configobj dependency is redundant. :)

Two things..

It's a bit cryptic and it's something we could do elsewhere. I'd suggest adding this to mint-common instead.

[kernc]

What is cryptic?! Only the regex is cryptic (as it ought to be), but I assure it's as robust as possible, provided the assumptions hold true. But it's a simple 10-line function, surely not worth a dependency. And moreover, I coded it with full insight into what little config parsing is done here; I expressly advise against using it for general configuration parsing. It might bite you sometime later. :smiley: I would, however, drop tracking configobj from mint-common.
