Main window improvements.

- Place cursor inside the help window when it's first invoked (allows for quick peek and ESC to close the help window).
- Allow ESC to close the dialog (named "Which?"), used to clarify the help context.
- Allow CTRL+UP or DOWN to scroll the window by one line at a time, without moving the cursor.

- Fix quick link feature (F2) to recognize FUNCTION names ending with single or multiple sigils.
- Fix external procedures being considered local and placed in front of program name.
