Overhauls pain message/status displaying, fixes oxyloss. (#9173)

Pain message/status displaying has been unified into custom_pain. This might cause some weirdness with when people go unconscious or get paralysis from excessive pain.

Oxyloss has been fixed and so has the oxygen damage overlay, which is now back. I'm not sure of the actual impact this has on damage.

Also added a fullscreen BIG RED overlay when you have BIG PAIN.
