Solves bug "Upcoming events query does not return results because the path is not correct, remove the path because it is not needed"

Solves #100 (BUG: Upcoming events banners (subsets displayed in Homepage and in News page) do perform the same search than the Upcoming events section of the Events page)

Solves #99 (Rename field presented_by (displayed in the full view only) to organized_by in generic events)

Solves #82 (Bug introduced in issue #45: Side panel in page to share is not displayed to the site but below the main content) for generic events and webinars

Solves #32 (Title, breadcumbs and selected menu entry of the "page to share") for events and webinars

Solves #93 (Sort past events from the latest) and #8 (Add title asc as second sorting criteria in upco events, past events and presentations)

Solves #90 (In the events page, upcoming cards should behave idem than the same cards in the homepage: link should open the "page to share" version of the content)

Solves #88 (In the homepage, upcoming cards should behave idem than product cards: link should open the "page to share" version of the content)

Solves #87 (Load past event images in background to speed up event view's load time) to solve “Some “page to share” of event don't open”

Solves part of #38 of sdswas.customviews (Add partner logos to all footers not only to the ones with a subscribe form widget)

Use class added in #62 of sdswas.theme (Links in the Modal window's details section can make the section so wide that it does not fit into the right side of the window)

Solves #60 (Make all content fields that are text indexable through the search across-site,search can be partial) for events and webinars

Solves #76 (Upcoming events title missing in the homepage's banner cards and in the News page's banner cards)

Solves #37 for Webinar and Generic Event (Set gray background to the buttons that allow to download documents)

Implement "No results" view of Upcoming events section in News page (same implementation than in Events page)

Move "No results" view implementation of Upcoming events section in Events page to a macro (to be used in News page too)

Add field “Register URL” to the webinar form and display both the “Register” button and “Add to calendar” button in the view while the event has not finished
