Added a music mute button and music convars to all music-playing randomats

- "My planet needs me!" now checks for body-dependent roles like the hypnotist before triggering
- "Copycat!" no longer triggers unless there are at least 2 traitors alive
- "Triggered" is now disabled by default

Disabled by default "First come, first served!" randomat as it doesn't really have an impact on the round in practice

- Fixed players forever sprinting when basics event starts if sprinting as event triggers
- Fixed being able to use non boomerang weapons during boomerangs event if weapon stripping is enabled
- Sharky and Palp no longer shuffles roles to fix not getting role weapons and to be less confusing

Hopefully fixed bus prop being an error model

Replaced "The Bucket" randomat with "The Bus" randomat

Updated randomat base and fixed lua error in base function

Hopefully fixed duos battle royale event not displaying winners properly

Fixed several issues with the 'Take a seat!' randomat:
- Fixed the rythian model being given out twice
- Fixed some chairs being in the ground
- Removed chair models that are annoying in first person
- Fixed players not being chairs if the rythian model isn't installed

Replaced the FOV change make a randomat effect with a movement speed change effect instead
