Fix M16 damage

[Richard-L]

Another find by Arsunt:

it seems Core made a bug with M16. If you shot while running, it supposed to reduce M16 damage from 3 to 1 and accuracy from 4 degree to 12 degree. But they made a typo, and reduced accuracy and damage of grenade launcher. The cool thing is that grenades are individual objects and their damage is hardcoded, so reduced by M16 accuracy and damage didn't change anything for grenades.
But I think I must fix this bug, so bye-bye good M16 damage while running

Probably something people want optional as they're so used to the (too) good damage the M16 does.

Some more explanation by him (if it's relevant):

M16 is an "Lara with M16" object ID LG _M16 is a weapon type index
Weapon table with damages and accuracies uses weapon type indices So since this ID is equal to grenade launcher index...
The funny thing would be if Grenade Launcher used these values.
But it does not.
