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

Remove unused code after having changed the implementation of “Add to Calendar” button (instead of creating a Google Calendar entry, now it downloads an ics file)

 Remove unnecessary import from the event view and solves bug “Event’s duration is empty if the option ‘Whole day’ event is selected”

In the Past Event grid of the Events page, implement the “no search results” view (Diana’s proposal)

Show text in the Upcoming events section of the Events page when there are no Upcoming events following Diana’s proposal

Solves bug "Add to calendar" and "Register" buttons are not displayed if the event is upcoming but has already started

Set image field to be mandatory in events because when they are upcoming it is needed in the upcoming events view

Solves bug “For event that last more than one day, the duration field  is not properly computed and it is showing one day less than expected”

Do not show Presentations section either if the folder does not exist or it is empty or only contains unpublished items
