PPSSPP iOS Port

The button stuck problem exists even on the Android version since the first days.
On racing games, like Moto GP, it's impossible to accelerate and use the analog stick at the same time.
That affects even gamepad apps, that emulated touch input.
Another thing is, that analog and d-pad are to close together.

Since the emulator reached a state, that it's more as a "proof of concept", improvements for input and button mapping should be done.
