SkyratBot 41aa1d2ee4 [MIRROR] Adds a colorblind accessability testing tool [MDB IGNORE] (#11995) 
* Adds a colorblind accessability testing tool (#65217)

* Adds a colorblind accessability testing tool

I keep finding myself worrying about if things I create will be parsable
for colorblind people. So I've made a debug tool for approximating
different extreme forms of colorblindness.

It's very very much a hack. We can't do the proper correction required
to actually deal directly with long medium and short wavelengths of
light, so we need to rely on approximations. Part of that means say,
bright things being brighter then they ought to be. S not how people
actually experience things, but it's not something we can do anything
about in byond.

Anyway uh, it works by taking color matrixes, and using the plane master
grouping system floyd added to apply them to most all parts of the game
you would want to color correct.

There's some slight fragility here, but I couldn't think of a better way
of handling it.

We also need to deal with planes that have BLEND_MULTIPLY as their
blendmode, since that fucks up the filter. I've come up with a hack for
it, since I wanted to avoid breaking anything.

Oh and since I want it to apply to huds too I added plane masters to
represent them. I think that's about it.
