[DONE][QoL] Grenade Fuse Hotkeys

[Stone Lake]

In grenade-focused gameplay, clicking the screen for fuse timers (PrimeGrenadeState) gets repetitive.
So, I suggest hotkeys for selecting most often used 0, 1, (possibly 2, 3) fuse timers, and 1,2, (3,4) as default keys.
Also, cancel - "cancel" hotkey doesn't work in this screen, only RMB.

Added hotkeys 0,1,2,3 (not 1,2,3,4).
Added cancel hotkey.

I forgot to write that Q can also be used as hotkey, same function as hotkey 0.

Thanks, that seems like a decent substitute.

There appears to be a side-effect to using 'Q' hotkey for zero. If you use this in the pre-battle equip screen, it also opens up the 'Q' search bar.
This might cause some issues if you use other hotkeys afterwards, because the keypresses will be added to the search string.

If you report a bug here, I will forget about it in 10 minutes and never return to it.
