[MC-19939] W7 sleep mode causes game to crash

Closing the lid of my laptop puts it into sleep mode, this seems to cause the keyboard instance to be removed.

'fun' facts:
-I tested it on 1.6.1 pre-release, but I remember this happening before 1.6 too.
-It only happens in full screen mode, not in windowed mode.
-Only happened with sleep mode, hibernation didn't cause my minecraft client to crash
-Happens with and without resource pack/texture pack(in previous versions)

I guess catching and waiting for the next available device should suffice, but that's for you guys to decide
