Amstrad PCW driver step I (#4873)
* pcw.cpp: Fixed correct floppy types per machine * pcw.cpp: converted debug and log messages to logmacro.h convention * pcw.cpp: fixed some more LOGs, replaced a sprintf and added the actual crystal value * pcw.cpp: slow down 4Mhz by 15% due to video circuit stealing cycles accessing RAM * pcw.cpp: fixed printer/monitor palettes and set a simpler default layout at startup
