[C-BIOS] C-BIOS 0.19 released

[Maarten t. H. <ma...@tr...>]

Hi,

C-BIOS 0.19 is now available.

Summary of changes between C-BIOS 0.18 and 0.19:
* Added support for SCREEN4 and SCREEN8.
* Added support for clock chip.
* Added support for palette. This fixes a lot of wrong colours.
* Stubbed many calls: non-implemented calls print their name on the openMSX 
debugdevice (if present).
* Various bug fixes.

Thanks to everyone who helped: Vampier who did loads of testing again, BiFi 
who implemented the clock chip routines and most of the palette routines, 
Manuel and Joost for writing stubs and in-source documentation.

Bye,
		Maarten
