[Coco] BASIC and Disk BASIC version numbers

[tim lindner]

Color BASIC came in versions: 1.0, 1.1, and 1.2
Extended Color BASIC came in versions: 1.0 and 1.1
Color Disk BASIC came in versions 1.0 and 1.1

These are three different programs that work together to bring you
Tandy's BASIC experience. They can be mixed and matched.

If you only have Color BASIC installed it will display its version
number. When you add Extended Color BASIC, its version will be displayed
and Color BASIC's version is suppressed. And if you have Disk Color
BASIC (which requires Extended Color BASIC) it will display its version
number, suppressing the other two.

The ROM in a CoCo 3 is a single chip containing Color BASIC 1.2,
Extended Color BASIC 1.1, and additional code to startup the CoCo3, and
add new BASIC commands. It displays the version number: 2.0. If you add
Disk Color BASIC 1.1 it will display 2.1.
