Z64k v1.2.3 - Pixel exact emulation of the Commodore 128,Commodore 64, VIC 20 and Atari 2600

• Update of character base address should be applied immediately (VDC register 28, confirmed with VDC split test program). Re-enabled Character Vertical Size(VDC register 23). VDC 101 100% supported now. :)
• Improved latching of VDC char base address.  Almost there... Artifacts between logo and scroller of VDC101 no longer appear. Still need to fix smooth x scrolling for logo and remove artifacts above logo.
