DSEmu bug fixes

I've pushed some patches through to the DSEmu Nintendo DS emulator source code repository to fix some graphics bugs reported here.

The patches fix the following problems:

• 256 colour mode 5 now works. Previously the bitmaps displayed incorrectly.
• 16 bit mode 5 now works. This was broken in 0.4.9.
• A crash when scrolling beyond the bounds of a bitmap in mode 5 has been corrected.

Unfortunately I had to roll back the thumb emulation fix from 0.4.9 as it caused problems with mode5 rendering in some demos. This has the effect of making some other demos crash that use thumb at various points. I'll have this fixed before the release of 0.4.10 in about a week.

I've also started working on getting the other graphics modes and sprites working. Although that is likely to be 0.4.11.
