ToDo
----
- Implement CD playing.
- Implement CDDB lookup for CDs.
- Can I do something about the CPU spikes (~40%) during MP3 playback? (thread?)
- Is there an alternative to GetRawText() in id3lib? (GetRawUnicodeText())
- Do something to speed up the loading of songs (maybe don't store
  AudioFormatReaders?).
- Implement m3u support (for internet streaming mainly).
- Get command-line file loading working properly on Windows (need to parse for
  "s - it'll affect Linux too, but less often).
