New for this release:
* Display aspect ratio much improved, a display aspect ratio of 2:1 is now

* ROM based (tape machines) models emulation. Each ROM model can
be configured to determine what BASIC, PAK and NET ROMs to use.

for disk emulated models can be configured for each model.
* Added specific disk emulations for 128K, 64K, 56K models.

confirm the requested actions. (in Windows only)
* Added --pcg option to select amount of PCG RAM for emulation (Premium).

This now defaults to 2K allowing some incorrectly coded programs to work.

* Improved error reporting.
* Added alternative shortened 3 character file name extensions for raw
images.
* Other '.dsk' image formats including 3.5" Microbee Modular images should
now be possible.

Fixed:
* Windows port now starts up correctly without a back ground command prompt
window appearing unless an error condition or if an information output
option is used.
* Fixed bug preventing '.DSnn' and '.SSnn' raw images from being opened.
