Subject: Adding ability for sounds to be added/removed on the fly

This adds a watcher to the directory named in localAudio (currently
doesn't check anything that may be in a child directory). Whenever a
file is created/deleted/renamed, it has the LocalAudioManager update its
sounds so they can be played.
