Reimplemented broadcaster so it can send 503 when a connection is in

place. Removed qcma/cmaserver class and reimplemented them in cmaclient. Make sure that the scanned files are sorted by filename. Implement filters so the database doesn't pick up unsupported formats. Implement album cover display for album listing in the vita. Fixed bug with streaming of pictures in wireless mode. Some code refactoring.
