The differences between STE and Mega STE (and also between ST and Mega
ST) seem to pop up every couple of months... So just a thought for
discussion: Should we maybe finally introduce the Mega ST and the Mega
STE as real selectable machine types in Hatari?

Mega STE is already available as machine type in the sources thanks to
some work of Nicolas in the past already, so this just (?) needs to be
added to the GUI, and we've got to do some more fine-tuning like the
difference between joypad ports vs. the DIP switches. (Can somebody
list all other differences between the two machines?)

Mega ST ... we could maybe define this as ST + Blitter + RTC, and then
get rid of the selectable Blitter and RTC options in the GUI. These two
options were also often causing confusion in the past: Users wondered
for example why they could not enable the Blitter for the TT machine
type (or disable it for STE or Falcon) that way. The only disadvantage
would be that you could not emulate a plain ST with a blitter
anymore... would that be an issue for anybody?
