Untangled the audio and video track from each other, and the parsing
of the stream from the decoding of its data. Also fixed a memory leak
as it turns out deleting a Surface doesn't free its data. You have to
call free() in it.
I have only checked the intro, not every cutscene, but that seems to
work fine at least.
As an alternative to using the Screen class's functions, we can let
the VQA decoder draw directly to the backend. This won't work if the
game uses "hi-res mode", but I don't think that's ever the case for
Malcolm's Revenge. I believe the KyraEngine_MR::playVQA() function
ensures that the screen is properly updated after the movie has
finished.
This almost limits the VQA rewrite to vqa.cpp and vqa.h. Whether it's
better this way than changing the Screen functions to take a 'pitch'
parameter...? I don't know. But it's an alternative.
* Use setScreenPalette() rather than calling the backend directly. (As an extra
bonus, the VQA player now only needs to store 3 bytes per colour.)
* Hide the mouse cursor while the movie is playing.

* The VQA move player isn't as similar to the WSA movie player as we first
envisioned, so the VQA player no longer inherits from Movie. It does retain
a fairly similar calling interface, though.
* Use the Kyra engine's idea of screen dimensions, rather than the backend's.
