DGDS: Refactor to split into smaller files
...
Split TTM and ADS logic into their own files, and separate palette management
from image loading.
Also refactor scene types a bit to be more objecty.

situations.

DGDS: More tweaking to rendering to match originals
...
This is still not quite right. I will need to add a mask layer it seems, as
running TTM opcode 0020 (save background) after drawing a color 0 rect is *not*
the same as running that opcode after just drawing a bmp on the foreground.

The first part of the intro now runs again! And now it's all running in the
way it's supposed to - script states are being controlled by scene ops as
designed, rather than just running through them in order.

DGDS: ADS and TTM implementation
...
* Rename TTM objects to match original ideas of environment and sequence
* Implement more ADS stuff in line with original - states etc
* Implement sceneop 4 which changes ADS states
Currently this breaks everything (no scenes execute) but the implementation is
far closer to the original, so it's a necessary step to get to a correct
reimplementation.
