I still have no strong opinions for or against this pull request, but it does have things that need to be changed like also not trying to arrest things with a high enough invisibility var

todo:

• fix the existing is_visible() proc to not be retarded (seperate PR)
• use is_visible() proc in this PR
• make secbots have an upgrade to go after invisible people

🆑

• tweak: Beepsky no longer arrests people that are invisible via alpha var

I like my idea of moving invisible arresting ability to an upgrade involving t-ray scanners but I don't know if anyone else does.
In justification of invisible arresting other than "its fun," it is also something that keeps invisible wizards/traitors from being god like. Other counters include the t-ray/p-ray scanner lines, water, thermals(?), mouse-over text, blind firing in the halls, and possibly HuDs such as sec and med if that hasn't been fixed yet.

I would be in support of being able to add a t-ray scanner upgrade to let beepsky keep his ability to show JUSTICE to invisible perps.

Beepsky tug of war where sneaky coders pull out the most insidious tactics

[FudgePucker]

Also there isn't much of counter play to invisible antagonists.

Getting close enough to a wizard with a cloak to see them with a t-ray scanner is a death sentence. And the CE isn't going to receive a weapon to help hunt until it's too late. Seriously, even though I am a head, it's like pulling teeth to get a laser gun for carp.

Can't be a main something when you don't play. Checkmate, vox metaclub leader.

Invisible hazards/threats are dumb and there need to be a way to deal with them
Beepsky was reasonable enough

[Intigracy]

I'll need to fix is_visible before anything else
