qemu Ctrl-Alt

While have to work with qemu, I noticed nasty thing - when one often
switches backward-and-forward between guest and host, qemu (or guest?)
goes insane about Left Ctrl key and assumes it's pressed constantly.
Boom, believe me or not, guest becomes totally unusable.

By default qemu use LCtrl-LAlt to grab/release input. I changed it
to RALT - it's not that I use this key much anyway, I'm not even sure I
ever did.

"If you can't live with it - patch it!"
