- Updated title music with a version provided by aeronic which fades out
more gracefully
- Removed attack SFX as it was included in the movement processing, but
will return later as part of a similar chunk of code which processes
combat sfx independent of movement.
This was failing to trigger since we now have a MovementState::Fall, but
the sfx mapper was still trying to work this out itself based on
velocity. We no longer need to track velocity as a result and can use
the MovementState.
Also silenced warnings resulting from unused vars when running tests.
This is an event based approach to SFX sounds. There is a specific
character sound event mapper which determines sfx to play based on
character or NPC state, as well as emitting sfx events for
non-character-triggers such as levelling up.
