TTY and COLOR WHERE attribute

All type of fields now allow TTY attributes and the conditional COLOR WHERE attribute.

Before version 2.00, only some field types like EDIT or TEXTEDIT could support TTY attributes (COLOR, REVERSE), and the conditional COLOR WHERE attribute.

Starting with version 2.00, all type of fields now allow TTY attributes and the conditional COLOR WHERE attribute. So when using any ATTRIBUTES(tty-attribute) in programs, all fields will now be affected.

For example, CHECKBOX and RADIOGROUP fields will now get a colored background, this was not the case in prior versions.
