IvyEngine: Generic Configuration Framework

[endy]

Create a basic framework for configuration of application settings.

It should allow for core and specialized configs at the engine and application level respectively.

It should support both command line and file based configs, with higher priority given to command line params.

This is almost completely finished. I need to test config files and implement the remaining config value types (only UINTs supported now).

I wonder if I should establish an IConfigurable interface for classes....

Will anything other than the App itself be configurable? Probably but not much at this point so might be wasted effort.

Consider this before closing the issue.
