[CLOSED PR] Removes numbers from health scanners on RP

[Zamujasa]

Crossposting what I said on Github:

I said this in the admin channel as well, but I don't like it.

it's going to annoy people with "great, how much is none/minor/major/life-threatening, what do all these words mean, and why are they changing position so it makes it harder to read at a glance"; the thresholds aren't clear, and you can conceivably be dying with three "minor" and one "major".

People already dislike the Health Implant HUD because it severely muddies the ground between the standard 100-80-60-40-20-0 health meter scale by replacing it with four even less clear icons; this is doing that, but for everyone.

There is also the obvious slipperly slope argument to be made; do we have to start obfuscating reagent amounts from scanners?
