About the pull request

Instead of checking in screen in relay_render_to_plane, we check an alist that exists specifically for this purpose. This ensures we don't have to loop over the entire screen list searching for each relay. That saves a ton of overtime.

We also don't recreate the planemaster's relay if it already exists. This seems to have saved the rest of the overtime, because now it's extremely low per call.

Explain why it's good for the game

Reduces overtime from 1.93568 per 292193 calls to a projected 0.2783 per 292193 calls (actual numbers are 0.002/2100, so it could be slightly better in practice due to rounding).

With a second change, I was able to get it even lower: for spamming F12 to call show_hud() over and over again, it was 0.001/6755, which is 0.0433 overtime per call. When spamming aghost and Re-enter corpse, it actually had an overtime of 0 for 3465 calls, which is incredible. Everything looks fine as well!

I would feel most comfortable if this was testmerged, but it seemed alright in local testing, at least.

Testing Photographs and Procedure

Runtime map looks fine, stairs aren't broken, openspace isn't broken, darkness/lighting isn't broken.
