Willie Pete, Pipe Bomb & Fragmentation Buff

[WeNeedMorePhoron]

About The Pull Request

Writing changelog and reviewing this myself tomorrow I need to sleep

• oh god i forgot to add WP to antag list i'll do that tomorrow too

• Add White Phosphorus Grenade from upstream

• Add craftable pipebomb from upstream

• Buff fire stack damage by roughly 2x (After finding white phosphorus grenade underwhelming), such that being on fire will at max stack will likely knock you down in 1 minute

• Partially ported upstream 7025 and 7187 - Buffed Fragmentation Nade (Frag Nade have base blast radius), added in Hesh Rocket. DID NOT port in the Stinger grenades (we have our own copy), disabled grenade ricochet because I crashed local while testing and is not 100% confident it won't crash

• Tiny bit of nerf of direct fire rocket (upstream parity)

For some rudimentary testing:

1. Pipebomb with a naked guy laying down - 300 damage brute
2. Pipebomb 1 tile away naked - 190 damage
3. Grenade with a naked guy laying down on top - 690 damage
4. Grenade with deepflare void suit on top - 70 damage (still knock you out)

(tested more extensively than this but this is the numbers I remember from my last batch. I tried my best to make sure everything is working)

Why It's Good For The Game

More crimes, more bomb, more authority. (Buff frags and stinger a bit, but also give more chances for tunnel snakes to get back with pipebomb)

While in the process of testing this PR I've realized that upstream have a fragment on wall duplication problem with grenade launcher that I am unable to fix yet.

Closing until I figure out a solution to this issue.
