Message Functionality Enhancement #1

Currently you can only /s to save or /a to abort.
Let's add /e to edit, /l to list (with line numbers) and /p to preview (without line numbers)
/e will prompt for a line number
- once provided the system will print out the current line
- then prompt for a new line to replace it with
- if new line is longer/shorter than old line, then shift bytes to accommodate
- add word wrap if possible (unknown, as this straddles BASIC and ML)

OVERALL PLAN:

Modify 5009-5010 to provide expanded options in help dialogs
5017 if i$="/e" or i$="/l" or i$="/p" then 5200
5200-5299 will branch off depending on action
5299 goto 5015
5300: edit
5400: list with line numbers
5500: preview
need to ensure user cannot edit any header lines

Edit was a little tricky, but I think I have it working. Did some edge case testing, and it passed.

Also, word wrap is possible, as all the code building I$ is in BASIC. Added some additional code in 400-499 (specifically 440+) to facilitate word wrap.

Also added Delete. Updated the help/tips. Tested extensively - still some edge cases where it doesn't work 100% properly (ie: often get a dangling CHR$(13) at the end of the message, and it can't be deleted) but overall seems okay for general usage.

Will deploy to prod!
