Added the ability for a viewmodel to disable the arms skin mesh entirely, useful for clothing like hazmats where we never want to see the skin
Added a clip mask feature to the skin shader, allows us to mask out a particular area of the hands
Exposed a clip mask texture field on the ViewmodelClothing component so we can declare a mask per clothing item (eg. show the skin up to where a set of gloves begins, mask it out underneath the gloves though)
Only current issue is that the clip mask doesn't work with the viewmodel camera, will need some shader help for that
