A_WeaponOffset Extension: WOF_OFFSET

[The Zombie Killer]

https://github.com/rheit/zdoom/pull/663

Adds WOF_OFFSET, makes A_WeaponOffset offsets a "true" offset, independent of absolutely everything except A_WeaponOffset.
Allows you to safely use A_WeaponOffset when functions such as A_Lower or A_Raise are running

This cannot be added without trashing the multiple PSprites submission so it will have to be redone.

I have no problem re-doing this if the multiple PSprites submission gets merged

I don't think this will be needed with how the overlay stuff is going to work now. One can specify whether one wants the weapon to be followed or not. I could be wrong though.

Unfortunately, it seems that PSPF_ADDWEAPON does not solve the weapon selection issue like this did, therefore I'll likely re-do this pull request when I have time

Hey TZK, any updates? I'd like to finalize my weapon sway code resource soon since I have some spare time right now. =D

[The Zombie Killer]

Unfortunately I still have little time (in fact my free time is shrinking rapidly D:), but I might be able to get something done this weekend

I am looking for this option, what is it called?

PSPF_ADDWEAPON.
