Add utilities for writing and reading to config/options

[DunderRoffe]

It would be nice to easily read and write to confg / option files.

Idea of how to implement this:
Create some generic read/write to file Class that is easily extended to something that handle some specific file type.

Additionally it would be nice if the utility assumed (unless given path starts with '/') that all references were from a data folder located were the game is installed.
