Datatables v2 SearchPanes client/server side

[thomas-topway-it]

• Fixes https://www.semantic-mediawiki.org/wiki/Help:Datatables_format#Limitations (searchPanes now works in conjunction with Ajax, i.e. with distinct values for each pane computed server-side based on the actual query)

• Fixes https://www.semantic-mediawiki.org/wiki/Help:Datatables_format#Known_issues (SearchPanes work correctly also if cells contain html)

• (redesigned) the parameter datatables-searchPanes is now used to toggle on/off searchPanes independently by the "P" symbol in datatables-dom

• adds custom parameter datatables-searchPanes.minCount (to include in searchPanes only items with occurrence greater or equal than minCount)

• adds custom parameter datatables-searchPanes.htmlLabels to toggle html/text only in panes' entries

• updated default separator for multiple values in cells (now is , )

• searchPanes support category printout

• searchPanes support dates ranges, and other grouping performed using printout formats

demos:

• categories and dates range: https://fina.knowledge.wiki/Test_Datatables/SearchPanes_Categories
• Noajax (all data are retrieved on page load) https://fina.knowledge.wiki/Catalogues_of_Numismatic_Collections
• multiple filters https://fina.knowledge.wiki/Test_Datatables

Some UX feedback: when selecting a filter on the left, I would find it more intuitive for the filters on the right to also update.

do you mean with subcounts ? if yes, this is theoretically possible (implemented in the original SearchPanes library)
