Minor Stinger Grenade bugs.

[Grifflez]

Stinger grenades are pretty nifty. Spiffy. Unique.

They also are super buggy!

1. Stinger Grenades that go off on the tile someone is standing on will not hit them with any shrapnel
   
2. Stinger Grenades in a mousetrap will not have any effect when they detonate. Huh.
   
3. They default to 3 seconds on the pin, but the safety box says 10?? And when set to 10 they explode at 3 seconds still??
   
4. Stinger Grenades do not have a small chance to be replaced with a bee grenade, which is basically the same thing but the sprite is a yellow and black pattern grenade instead of the urine-color and grey metal it is normally.
