Some minor VQA player fixes:

* The playVQA() function now takes the name of the cutscene, rather than the
  filename. This is so that playVQA("FOO") will be able to play FOO0.VQA,
  FOO1.VQA or FOO2.VQA, depending on which movie size is selected.

* The VQA player centers movies by default, so don't set the position to 0,0.

* Ask the backend for screen dimensions (for centering the movie) rather than
  hard-coding them.
