This PR was originally just going to be a re-factor of brig doors to be based on status displays, as a big chunk of their code was duplicating the exact same appearance, but then I realized "Cell 1" would have marqueed for being 6 characters and ended up doing the second half of the status display overhaul I meant to do a while back.
So firstly:
Yes, brig doors are now subtypes of status displays.
The main improvement out of that refactor, other than a lot of code trimming, is that the on-screen timer updates its readout as you set it, which looks nice.
Also handled various states in a more consistent way in some edge cases.
The timer now also displays the cell's actual name instead of the internal ID on the top line.
Now for status displays:
Long ago, I wanted the marquee to be continuous but the math required knowing the actual measured text width, though without a user that is impossible.
I recently realized the scope of the text usable on status displays (no formatting, or icons) is so narrow, I can cheat it like crazy into a small lookup table and a looping function.
No, this method can't possibly extend to runetext.
So now the marquees loop seemlessly without any gaps! In fact behind the scenes they loop the very first pixel possible, and still done as a one-and-done animate() sequence as before. (click the preview below if you want to see it smoother)
Status displays are now a bit more colorful and have gapless marquee text.
Brig door timers were massively refactored behind the scenes. Door control should still work as before but be mindful.
