Remove unused sounds

Done with the following script:

```ruby

tsv = File.read('assets/txtdata/sound/effects.tsv')
all = tsv.lines[1...].map {|l| l.split("\t")[0]}
used = Dir['Source/**/*.{cpp,c,h,hpp}'].flat_map do |path|
	File.read(path).scan(/SfxID::[A-Za-z0-9]+/).map {|s| s.split('::')[1]}
end

used.concat(%w[
	Warrior69b
	Sorceror69b
	Rogue69b
	Monk69b
	Swing2
	SpellAcid1
	OperateShrine1
	Warrior14b

	Warrior2c
	Rogue14b
	Rogue14c
	Sorceror14b
	Sorceror14c
	Monk14b
	Monk14c
])

used.sort!
used.uniq!
unused = all - used
unused.sort!

File.open('assets/txtdata/sound/effects.tsv', 'w') do |f|
	f.write(tsv.lines[0])
	tsv.lines[1...].each do |line|
		fields = line.split("\t")
		if unused.include?(fields[0])
			puts fields[2].tr('\\', '/')
		else
			f.write(line)
		end
	end
end
