New SFX sounds.
add_item.wav (Better fitting pickup sound)
drop_item.wav (New sound for dropping items)
open_inventory.wav (The old pickup sound, can be used for opening the bag but needs to be implemented)
sword_in.wav (Better fitting sound)
sowrd_out.wav (Better fitting sound)
Fixed the drop sfx sound in sfx.ron
Its the drop_item sound instead of a grass moving step.
Implements a potential structure for splitting the SFX event mapping
into smaller individual files for maintainability.
- Remove inventory events for now: For a later commit.
- No longer panic when there is a failure parsing the sfx file: log the error and not play sfx.
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.
