- renamed the eye_stat var to eye_damage.
- mob/on_varedit() added. Manually var editing a mob's eye_blind var properly updates his vision.
- I removed update_vision_overlays(), we now just update the relevant fullscreens instead of all fullscreens whenever one needs to be updated.
- fixed climbing into mecha not giving you mecha sight.
- simplified and removed copypasta from update_tinttotal() (now update_tint() )
Fixed Xray users getting vision impairment overlays when inside a container.
Fixes mob inside mecha getting the mech sight flags despite not being the pilot.
"get_vision_impairments" is renamed to "get_remote_view_fullscreens".
