decreased range of random sound_key that gets generated when broadcasting a tweet to 1-5. Using this we send a hardcoded mappings object to the client right now for the development phase
added a utils module to the client that serves helper function like inherits. Added the latter to the locator and websocketConnection class
added a BufferLoader module that does XMLHTTPRequests to the server to fetch the sound files and performs decodeAudioData in order to get proper audioBuffers for our application.
The decoding is async actually takes a while. We should definitely add some feedback for the user here later...
