grapefruit grenade

--[[
Script Version 2.1
Changelog Revision 2

Grapefruit grenade, a nickname that US Army troops named their
fragmentation grenades because they (somewhat) resembled grapefruits.

Script by DarkShadow6

Changelog:
 o 2.1
    o Updated with love from Five-seveN. Limb controllers fixed.
 o 2.0
    o Started changelog.
    o Revamped script. The hopperbin no longer stays in your backpack after you throw it for like 3 seconds.
    o Made it blue.
