## About The Pull Request
Most instances of /obj/effect/portal now faintly glow their respective
color.
This was taken in the dark, the glow isn't as noticeable in the light.
Anomaly/jaunter/mech wormholes do not glow, since they use the
black-and-grey swirly sprite and don't look like they'd emit any kind of
light.
Also autodocs some portal related vars and changes one proc to not use
single char vars.
I also tried adding a soundloop but it sounded kind of crappy so I
decided against it.
## Why It's Good For The Game
Makes the portals a little bit prettier :)
