copy the current config when creating a pre-game config

I don't care either way but I guess this makes it more practical, because you can reset to defaults but you can't copy any other way (except for copy/pasting the *.ini files).
Consider:
1. I start PPSSPP fresh, no settings yet.
2. I change the global setting "Vertex cache" to off.
3. I start playing Crisis Core.
4. I create game-specific settings for Crisis Core and apply various speed hacks.
5. I decide that the speedhacks are causing trouble and reset "to defaults."

I'm not clear on whether Vertex cache will be on (ostensibly "the defaults") or on (global settings), nor what the user's expectation will be.  "The defaults" and "their defaults" seem ambiguous here; I think the wording would need to be clearer to convey that the settings will be reset to the *original* "factory" defaults if that's what it does, and should use other wording if it resets to game-global settings.
