Show_Submission/extract_images: some tidying, addition of more POD
documentation.
Show_Submission/query2csv, Show_Submission/query2json: these softlinks
were turned to hard links to make them more visible in the Git repo.
The files are in the 'Database/' directory.
Show_Submission/extract_images: removed unwanted modules, added POD
documentation, added 'coalesce' routine, adjusted to use the
absolute paths to the input files and generated image files. The
latter are always written to the directory where the HTML resides.
Corrected logic around overwriting image files and '--force'.
Still an 'alpha' version subject to more testing.
Show_Submission/extract_images: new script to read an HTML file looking
for 'data' scheme URIs (embedded images), extract them and modify
the HTML to reflect the new source of the image. At present it
writes a generated file name with a sequence number in it, but the
appropriate suffix/extension for the image type. This is an alpha
version which needs further work.
Show_Submission/parse_JSON: attempting to debug a JSON parsing failure.
Show_Submission/author_title.pl: Added the subtitle field taken from the
JSON into the YAML
Show_Submission/do_pandoc_assets: New script to process Markdown assets
files. Not in use.
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.
