(MESS) gameboy, gbcolor: added a configuration setting

Browse Source 
(off by default) to skip BIOS checks at boot. This allows the 
recently dumped Rockman World Prototype to be played,
and the Rocket Games pirate GBC carts too. [Fabio Priuli]

(MESS) gba: added a configuration setting (off by default) 
to skip some BIOS checks at boot. This allows Tyrian 2000 
Prototype to be played. [Fabio Priuli]


out of whatsnew: for the Rocket Games pirates it is currently unclear how real carts were bypassing
the BIOS checks on a real unit, and it would be nice to emulate it properly. however, this trick allows 
to go on fixing the rest of mapper emulation until it's fully understood.
