Find/replace dialog, goto code definitions and other improvements.

Hey all, I've uploaded the latest version of my Pas6502, I hope you enjoy!!

The IDE has had some big changes:

• find/replace dialog box.
• mouse over code to show information, and navigate to code/unit definitions using Ctrl + Click.
• code insight for arrays of records now.

The code base has improved too:

• supports arrays of record types.
• various fixes.
