Wathe Train Utilities

Adds:

Train Watchers - Players who do not get teleported with the Teleporter Horn. Opting in/out is done via interaction stations. (there is a bug where after a game, they lose the gray name & suffix, the tag is preserved however, so it shouldn't be anything other than visual) Interaction Stations - 4 functions, each for one interaction entity, with some decoration (item displays): - Conductor's Horn - Teleporter's Horn - Opt-out station: Unsigned waiver is given to the player and player is added to Train Watchers - Opt-in station: Unsigned waiver is taken from player and player is removed from Train Watchers Conductors have access to Teleporter's Horn via interaction station Added sounds for interaction stations, and for certain actions [using Teleporter's Horn]

Fixes:

Refactoring and removing remnant/unused functions Modded games no longer have a chance to fail, due to picking an unavailable game start option
