support multiple copies of a facet on a page

close active PHP sessions during indexing to prevent progress bar stalling
the "No results found" string should be in the "fwp-front" textdomain
ignore all EDD hidden fields from the "Data source" dropdown

- fSelect styling tweaks
- admin UI - only pass Vue the necessary data (faster loading)
- admin UI - cleanup of redundant Vue code
- fSelect opacity issue when refreshing
- layout builder - only render link "target" when needed
- Vue reactivity issue when using the "source_other" field on newly-created facets
- PHP notice when "active_plugins" wp_option doesn't match plugins (usually caused by DB imports)

- admin UI - replaced FontAwesome with in-house SVG handling for faster loading
- query detection - only intercept the *identical* query (it was too lenient before)
