About the pull request

WIP

Design Document: https://hackmd.io/lfJWvwWSTEyxFs_nN2sIqw

The purpose of this PR is to change up Xenomorph Endgame through 2 features. Hive Buffs to replace pylon larvae and a new game-ender caste called "Destroyer"

Mainly putting this WIP up to motivate me to finish it.

Assets needed:

• [ ] Sprites for Destroyer spawner
• [ ] Footstep sounds
• [ ] Better ability sounds
• [ ] Pylon sprites for active hivebuff to replace my codersprites
• [ ] Sprites for hive buff radial menu to replace codersprites
• [ ] Sprites for ability icons

Code

• [x] Bulwark increase duration + longer cooldown
• [ ] Doom sound effect + black transparent smoke around the destroyer when using ability
• [x] Destroyer Leap needs full testing & refactor pathfinding
• [x] Use "no burrow" turfs to check for un jumpable areas
• [ ] Destroyer spawning code
• [x] Implement Ex-Act for destroy ability to act on structures/machines etc
• [ ] Full ability code review, check all plasma costs, status checks, xeno can harm checks etc
• [ ] Remove "BIRDTALON:" tag and act on notes.
• [ ] Full testing of hive buffs & conditions
• [ ] Remove to_chat(world) testing lines.
