Major media subsystem revamp:

- All images are loaded through the image manager
- Architected to allow the use of prepared or unprepared images (and
  volatile images when the day comes that they support alpha)
- Tunable caches for images and tiles
- Resource manager caches unpacked resources on the filesystem
- Various and sundry other cleanups
