Updates, fixes, and C128 support added

Hi all, for those who missed it, I have made recent improvements with Pas6502:

• some behind-the-code improvements.
• extra missing fragments were added.
• code insight additions were made to the IDE; Ctrl + P for code suggestions, and '.' suggestions for record types.
• Commodore 128 (C128) support has now been added, which makes 3 machines Pas6502 now supports.

I hope you enjoy the improvements!
