Config formatting

[caojohnny]

Configs currently cannot hold comments or integer values (they can only be floating point or double for whatever reason).

Seems to be a problem with saving the config itself

[nickrobson]

Is this a problem stemming from the Config class?

IMO, we should overall the config package into a more abstract method, with a JsonConfig implementation: allowing the possibility for other formats.

The config stuff is already quite well abstracted, I'm not sure what else would go into that
