Dropped weapons disappear suddenly instead of slowly fading
Unlike ammo and medpack, dropped weapons suddenly disappear after timing-out instead of fading away underground (like corpse).
A similar issue exists with satchel, when the covops dies before setting it off. See if we can make them fade too.
This would be a small visual improvement only, but I feel it’s very noticeable especially when using cg_simpleItems.
game: made dropped weapons slowly fading, refs #1334
Moved MagicSink function from g_weapon to g_misc and renamed G_MagicSink
