edited play_sound function to use paths if the sound name doesn't match any of Bukkit's sound names.

this is something VergilPrime wanted because of his custom resource pack addiction.

the main thing is that if does use paths it uses Bukkit's deprecated playSound function for it.
sorry if this pull looks ridiculous. i don't even know if i'm merging to the right branch or not.
sorry about those useless whitespace changes too.

(it also isn't tested, sorry)
