[zx] ZX Preview 2.0

ZX Preview fot@zx-modules.de

October 2011:

• Implementing new register tab "block info", which shows details of any data block.
• The picture register tab now can display a 64 color ULAPlus palette as a 8x8 color pattern.
• Implementing new register tab "debug info", which shows any byte-related data block in Z80 mnemonic. It's also possible to set a start address and to set a start and stop value.
• Activating printing reports of "block info", "hex editor" and "debug info" register tabs.

September 2011:

• Implementing icon and dialog resizing abilities (small, medium and large icons and text messages).
• I've added a scrollbox around the SCREEN$ view, so that bigger sized SCREEN$ can be displayed from all edges.
• Adding ULAPlus and Timex SCREEN$ support. The display routines have been completely renewed. The screen content is automatically divided into SCREEN$ and ULAPlus blocks, for better editing.
• Bugfix: There was a bug in the text column of the byte viewer: Spaces were not displayed. Now, also spaces are displayed.
• Bugfix: There was a very wrong display of INVERSE attributes in Basic listings: Instead of setting permanent INVERSE attribute, it was simply toggled by an occurrence of an INVERSE 0 or INVERSE 1. Very silly bug.
