- brought back the old l4d1 special intros nightmare had before they disappeared

- crosshair is removed when scoping with a sniper rifle

-swapped common damage script from melee rebalance to this script
-when taking damage, temp health is drained before permanent health

Made it so that every flashlight spawn in the world spawns a pistol instead. Considering how rare pistols are in nightmare and how weak flashlights are, this seems to be a fair balance.

should hopefully fix that annoying console error people keep mentioning

now you'll never know
