Support gamepad remapping

[davenewton]

The w3c gamepad specification allows browser to implement remapping of game controllers axis and buttons.

Adding a remapping gui to Firefox will allow users to:

• use their preferred game controller layout with web games that do not implements a configuration screen (most of them dont) ;
• use non standard game controller (like arcade stick or dance mate) ;
• dont rely on third party complex remapping tools (each are specific to OS / hardware) ;
• get a per domain / per page configuration ;
• use keyboard as a virtual gamepad to avoid problem with keyboard layout (WASD versus ZSQD).
