MKID_BE relied on unspecified behavior of the C++ compiler,
and as such was always a bit unsafe. The new MKTAG macro
is slightly less elegant, but does no longer depend on the
behavior of the compiler.
Inspired by FFmpeg, which has an almost identical macro.
Currently in some places the RGBA palettes are converted to RGB before they are
set up. There might be a better way, but this should work fine for now.
The game will start, but has many problems as it uses a later version of the LB code. Also, make sure we check for filename being empty to stop an assertion in the MacCursorManager.

Cursor handling has now been moved to a new CursorManager class (which is subclassed for Myst/Riven) from the GraphicsManager classes. This will be needed for Living Books which will have a class for Windows and Mac cursors (coming soon!).
