FTL Umbilical Tweaks

[Drulikar]

About the pull request

This PR is a follow up to #11368 doing the following to the umbilicals:

• Anchorpoint can randomly select the riot control ert now too
• Smoke now accepts time_to_live argument in Initialize - this is for the following change to not be overridden
• Smoke will now only have a random few ticks of time_to_live if in an area flagged as AREA_HEAVILY_VENTILATED
• Fixed weird initialize arguments for a shotgun smoke particle system
• Fixed boiler gas' lifetime_mult argument doing nothing (still is 1.0)
• Fixed umbilical doors not being explosion proof
• Added two long range, omni directional, premade sentries in umbilical airlocks that shoot at non-humanoids (and Yautja)
• Automatic door_controls can have delayed opening/closing and the umbilical doors have a 15 second open delay

Explain why it's good for the game

There was some internal feedback that xenos sometimes are just spawn camping people at the umbilical airlocks. Sentries should mitigate xenos getting too close and also counter stuns. The area clears smoke quickly so boilers cannot simply smoke a small area with a bunch of newly spawned players. And the doors opening not immediately allows atleast a little bit of time to get settled into the ERT character.

Changelog

🆑 Drathek
balance: Anchorpoint spaceport for FTL can now spawn riot control ert
balance: Umbilical airlocks now have two long range, omnidirectional, premade sentries that shoot at non-humanoids (and Yautja)
balance: Umbilical airlocks are marked as a new AREA_HEAVILY_VENTILATED to reduce smoke time_to_live duration to just a few random ticks
balance: Umbilical airlocks now open after 15 seconds to allow people a little more time to get settled in
code: Smoke now preferably overrides time_to_live argument in Initialize
fix: Fixed umbilical airlocks not being explosion proof
fix: Fixed a couple misc things regarding lifetime_mult not doing anything for boiler gas (no effective change) and weird cause_data for a shotgun smoke system
maptweak: Misc changes to umbilicals to place sentries, change the internal area, and add fluff scrubbers to better suggest the reason why gas clears quickly

Wouldn't it be funny if there was a small chance for low threat kommandos to come from UPP station?

I doubt it'd be much stronger than elite freelancers which ftl stations can spawn.
