Frag grenades buff (#20135)

Frag grenades projectiles now apply some agony and eyeblur.
Frag grenades projectiles have damage augmented by 3 points (~10%).
Frag grenades projectiles have an augmented chance of leaving a shrapnel
(+30%).
Frag grenades projectiles have a chance to ricochet up to 2 times.
Some code cleanup and removed some procs that were no longer used
(nothing called them anymore) from the projectile refactor.
