Add ability to reload rtx.conf

[BlueAmulet]

Sometimes it might be easier to tweak the config in an editor, or eventually people may make their own tools to work with captures or calculating texture hashes themselves. It would be nice if there were a button that could reload the rtx.conf to support these uses.

I have given an attempt at this here, it seems fairly simple but I am unsure how to integrate this baseGameModPath system into it.
