Fixed iron sights + added SWEP.ViewModelBoneManipulations

_(master branch)_

I went through all the weapons and fixed up the iron sights. Even ones that looked good before were perfected by temporarily enabling crosshairs and lining up the sights to that.

I also added SWEP.ViewModelBoneManipulations. I know DarkRP 2.4.3 is currently in a feature freeze but this was added _to fix bugs_. I've only used it in the M4 because it was the only one that needed it atm. See the below comparison and look at the hand (loading may be slow):

And here is the comparisons for the iron sight fixes:
(do note that the crosshairs were temporarily added purely for alignment and are disabled in the repo)
