Removing settings cancel option from gui

[NaN]

The GUI has a cancel functionality which allows to reset changes on the active page. To be honest, I find this feature completely pointless. Additionally it makes the GUI code a pita to work with. I would prefer to remove it. Are there any objections?

I kind of like the feature, but I'm fine with you getting rid of it if it makes the code easier to work with. Most games don't seem to provide such an option.

Would just replacing this function with a reset to defaults button make the code better? It's really useful for people trying out different settings. Makes things go faster.
