I think this does not make much sense. An STE with Blitter disabled is
no STE anymore. Better make the emulation code more speedier.

If you disable the Blitter you can really switch the whole emulated
machine over to STF mode.

I think it's more useful to improve the code instead of providing a
senseless disable function.

Also the timing of the Blitter emulation is not accurate according to
the Paradox boys (and they are heavy Blitter abusers on their STE
productions).
