[hatari-devel] better color alignment in spec512 mode

[npomarede at corp.free.fr]

Hello,

I added a better (hopefully) support for movem when changing palette with 
either movem.w or movem.l.

Previous version had a wrong 4 pixels offset when using movem.l

This fixes a small glitch in Dragonnels Menu, a vertical line in the 
Plasma screen of the No Cooper and the slideshow in the Place To Be Again 
Demo (note that the intro pic is still wrong, I need to figure out why).

No regression found in Tex old slideshow or Froggies Over The Fence or 
Lethal Xcess.

If you know some programs using spec512 mode that :
  - still don't look good
  - look worse with this patch

Just let me know, the more examples I get, the better results I should 
have.
