Add ZOOM_* versions of the regular weapon states

[dashodanger]

This would allow for alternate firing/reloading/etc animations based on whether or not the weapon is zoomed in versus our very much static current zoom state.

Actually we need to get the regular ZOOM state animating first.

You know, I saw that issue and thought it was actually a duplicate of this :/
