Change save folder location in Android

[lvlln]

I'd definitely really like this going forward. I too have a phone with little internal memory but with a large SD card, and having all my massive save states in the SD card would be very useful. I'm considering trying out making a symlink from the internal memory to the SD card as a workaround, though I haven't had much luck with that technique before in other apps, so I'm not hopeful. Ideally, PPSSPP for Android should have a setting where we can specify exactly where the main PSP folder should be stored.
