Moved the folder containing media, thought it was more suitable to put in main directory. Added four tracks for background music (at least for testing). Modified the Sound class a little to allow the BackgroundAudio class to accept a vector of strings containing the filenames of audio files.
Refactored Sound classes, client must call the startBackgroundMusic() function on their initialized BackgroundAudio class before it will begin playing audio, and must call the playAudio() function on their initialized SoundFXAudio class before sound effect will play.
Added class MySoundEndReceiver that is to be used to keep trnd music.
Refactored/updated more of the BackgroundAudio class. Functions the same as of right now, but for some reason I cannot get one line (commented out temporarily) to compile. Line 85 in Sound.cpp.
