Various updates

Show_Submission/copy_shownotes: Changed the location of the function library

Show_Submission/do_brave: Updates to the way local stand-alone HTML is generated for
    review purposes.

Show_Submission/do_index: Changed the location of the function library

Show_Submission/do_pandoc: Changed the location of the function library; now uses
    'author_title.pl' to generate YAML for Pandoc

Show_Submission/do_parse: Trivial change

Show_Submission/do_pictures: Changed the location of the function library; better
    handling of the show specification

Show_Submission/do_report: Changed the location of the function library

Show_Submission/do_update_reservations: Changed the location of the function library

Show_Submission/fix_relative_links: Added features 'say' and 'state'

Show_Submission/parse_JSON: New checks: notes too short, trailing spaces on title,
    summary and tags (needing JSON changes). Check for Markdown in the
    assets (see 'do_pandoc_assets'). New 'trim' function.
