Rewind (instead of F12)

[GoogleCodeExporter]

Since we have ghost saved (but for 1st player only in SplitScreen)
we could just have a Backspace key (or F12) that takes your car 1 sec back, 
pressing it again another 1 sec back and so on. (Or maybe it could be even 
"hold the key to rewind" behaviour ?).
So much better than the "go to last checkpoint" (where you could be in weird 
pos). Also rewind will not set velocity to 0, so you can rewind inside 
loops/pipes.
Still some issues may appear, need to mark somehow that you are rewinding so it 
won't get saved in ghost (for more rewinds later).

Done. I'll push asap, still no internet.
It works as: hold to rewind.
Made own class to save data (need vel, ang.vel), works nicely, also in 
splitscreen.
Default key is Backspace.
F12 is useless now, but: if you hit "wrong check" message, you mostly don't 
know which check did you miss.
