* initial OrbitalShuttleTimeMsg packet and tests; new objects to support HART shuttle transport system
* master was stale
* grouped scheduling for timing orbital shuttle activity
* door lock controls for HART shuttle lifecycle, and specifically for the doors that lead into the shuttle boarding hallway
* separation of the door from the door unlocking logic, which now has to be provided if performed by an outside source; a door that is locked either by bolt, HART routine, or other reason, can now be shut immediately; message when HART is not docked with a corresponding entry hallway door
* better degree of door logic control; all shuttle-related messages have been moved to LocalService; careful managing of 'original state' for the shuttle's cycle
* modification of seat mounting and cargo mounting support entities to expand functionality
* absolutely very little to do with the feature of this branch and a lot to do with yak-shaving; long story short, class inheritance is greatly modified and mountable seats can now accept multiple players if initialized properly
* a lot has changed: distribution of MountableBehavior, mount point information is more complex, vehicles convert differently, the routine of the shuttle timer is initialized differently; you can now successfully utilize the HART shuttle to drop into a zone
* swap of shutle from pad to pad control; tests and comments
* eject players from HART gantry hallway as if passengers dismounting from seat when not boarding through the use of environmental geometry; HART system uses duration from config settings to set scheduler
* rebase to curious master; repairs to vector rotation calculations; regression of mountable changes involving seats with occupancy greater than 1; orbital shuttle as a unique vehicle and amenity; corrected dismount offsets and offset calculations; weird angle of nc hart a building has been properly accommodated; hart events have prerequisite animation states
* rebase with master; looks like rebase with merged_master, which is also a commit
* lots of tests (though not nearly enough); checking the permission group of a shuttle seat no longer creates that seat
* fixing explosions
* fixed the persistence monitor service potentially using non-printable unicode in actor names
* can not use a droppod to gain access to one's own sanctuary
* removed hart facility update that causing open bay doors and beeping
* PR review changes
* fix for aggravation issues
* planar classes to describe levels of water and other fluid parallel to the ground
* corrected purpose of field in OxygenStateMessage and adjusted the structure of the packet; the environment is now 'regions filled with stuff'; messaging pathways to facilitate drowning and drown recovery in SessionActor, WorldSession, and PlayerControl, as well as the avatar event system
* drowning height is now a featur - recommend going through GlobalDefinitions; fixed lava pool collision to work on pool entry rather than drown level; lava now burns; painbox damage now is directed towards players control agency first
* drowning timer works correctly for both player and vehicle targets; timing and dive depth information for targets defined, but currently originates from a generic location (ObjectDefinition); packet OSM has been modified for efficiency; classes for environment features previously exclusive to drowning mechanics have been pushed towards generic naming conventions
* added sea and pools for z4, z5, z8, and z10
* vehicles now take damage (to the point of destruction) when exposed to lava due the expansion of environmental damage reasons and environmental damage modifiers; modification of the environment exposure lingo; streamlining of vital activity record system
* added basic drown params to flying vehicle definitions; object trait and control mixin for environment interaction, code moved from SessionActor and WorldSession
* separated environmental classes; handled waterlogged flying vehicles, in properties and code; wrote comments and tests
* players mounting vehicles and players subjected to the vehicle transfer process should receive updated drown-state status of the vehicle; drowning should suspend while in the middle of vehicle transfer, in the case the process is long
* increased damage performed to vehicles by lava
