[MIRROR] [s] Hallucinations 4.0

[yogstation13-bot]

Original PR: tgstation/tgstation#37423

No ingame changelog cause these are supposed to fool people.

Changes:

• Hallucinations now pick from a single weighted list, instead of being separated in tiers. The more obvious a hallucinations, the less likely it is to appear.
• Hallucination is now a contantly ticking down variable. 1 hallucination = 2 seconds duration. Hallucinating effects have been rebalanced to fit this.
• Hallucinations have a random cooldown ranging from 10 to 60 seconds. The status will still tick down in the meantime.
• The Sounds hallucinations has been split in three: realistic sounds (likely), weird sounds (rare), and station messages (i.e. the shuttle arrived, blob warning, etc.)(also rare).
• The Bolts hallucination now stops you from bumping doors open. You can still click them to open them.
• Removed the singulo hallucination. It's pretty much impossible to make it realistic enough, and it's too widely known to scare someone. It's an annoyance and a definite tell that you're hallucinating.
• Removed the xeno attack for the same reasons. It was kept in the code to serve as a pseudotemplate for hallucination mobs.
• Removed the fake attacker hallucination. Trying to replicate full attack and defense code as well as managing icon generation with blacklists and all is just not worth it. It would never be realistic enough.
• RDS hallucinations have been either rolled into normal ones or removed (the OOC ones). No reason to keep them separate, aside from throwing off the hallucination odds (which has resulted in complaints about the cult victory warning being too common).
• Added/edited a lot of strings for the text-based hallucinations. I could definitely use a few more for the message hallucination, i got writer's block there.
