* Polaris initial plane upstream merge
* POLARIS: Fix RIG visors with new plane system, and material scanner VIS_FULLBRIGHT
* POLARIS: Fix GetFlatIcon so that cameras and id pictures don't show the HUD overlays.
* POLARIS: Adds a 'alter values' proc for plane master ease of tweaking
Setting stuff like colorblindness variety and things.
* Remove NIF reference, fix lighting layer define
* Handle effects above lighting plane
* Moved all layer defines to planes+layers.dm
* Fixed overlays that are supposed to be above lighting to use the PLANE_LIGHTING_ABOVE
* Merge: 3000% human/update_icons() speed improvement
* Merge: Avoid ghosts pointing at things
update_clothing() has been broken up into it's key parts. A full explanation can be found in code/modules/mob/living/carbon/human/update_icons.dm
the tl;dr of it is that overlay updates are no longer called by the gameticker. Instead they are called by procs such as u_equip db_cick etc. This means faster updates (although admittedly, more of them can be called per tick). This however is offset by the fact that specific overlays can be updated now, vastly improving its efficiency. This will especially help when there are large numbers of dead mobs.
Fixed the throw code for TKgrab so it can be toggled.
Cloaking for aliens/humans/ninjas was changed. It's very crude at the moment and for that I apologise. But it works and is very efficient.It also stops cloaked individuals becomming invincible due to people being unable to hit them (even when they know exactly where they are)
Fixed a bunch of bugs with damage-overlays. They were updating FAR FAR to frequently. They were also horribly inefficient. They should now be virtually seamless when updating and only use cached icons, so they aren't affected by lag as badly. This may help with explosions lag a little.
There's still a tonne of stuff I need to refine with this. I'll be refining it down into some helper procs to reduce on code duplication and such
