LWJGL controller support

With a recent commit to the LWJGL cvs by Kevin Glass, we now have controller support again. This has been done using jinput and a couple of LWJGL classes to simplify access.
I have added a notice in the LWJGL readme about the jinput usage and a link to the site. Furthermore the jinput license has been added to the 3rdparty license dir.

Thanks (to the jinput team, and kevin)!

Glad its helpful!

Glad the recent changes helped. Thats exactly the sort of reaction I was hoping for when I suggested them :slight_smile:
