clear mapped keys buttons

[ZeroX4]

i wanna ask can we have here



3 buttons that would clear all mapped keys for specyfic device

like

clear all keyboard keys
clear all xbox gamepad keys
clear all usb gamepad keys

cause im kinda xpadder user (xpadder mapps keyboard keys to ur gamepad) so i can set any keyboard key to be used when i press certain usb gamepad button

and so when i download new automated build of ppsspp i need to manually delete all gamepad mapped keys in ppsspp so they dont make collision with xpadder mapped keys
