testing collapsible tables for mobile views

[thepigeonoftime]

This is meant as a test branch for collapsible (column to rows) tables for mobile views, it works through a Javascript that adds table header captions as attributes into corresponding <td> tags which are then prepended using CSS. When Javascript is disabled it falls back to scrollbars where tables overflow.

Things to consider:

• This currently applies to all <table> tags. If this is not intended it would be required to add an identifier class to the tables this should apply to and adjust the topmost querySelector in the script to it.
• Occasionally <td>'s seem to be used for annotation, e.g. This site is likely blocked because it can also be used as a censorship circumvention tool by acting as a web proxy. at https://ooni.org/post/indonesia-internet-censorship/ , this would be wrongly displayed as its own table using the current approach (but could be circumvented by giving those <td>'s a special class)
• The CSS markup for the collapsed tables might require some tweaking to fit into the overall design
