[FIXED] Expose rumblers in Controller

[Orangy Tang]

So I'd like to get vibration/rumble feedback when using a pad. Currently I'm flicking between Win7 and OSX/Snow Leopard to develop on, and using either 360 or PS3 pads.

Firstly, I added a small change to expose JInput's rumble:

Could this be added to the LWJGL repository please?

Unfortunately, on OSX with a PS3 controller it doesn't expose any rumblers. That might be JInput or OSX, I haven't got to the bottom of that yet. And I'm going to test on Win7 with a few pads soon and chase up how well they work (or not).

thanks, patch committed.
