RATIONALE

Events often have sponsors displayed on their front page. This should be
a real standalone feature of Online Event application. However currently it
cannot be used without tracks managements

PURPOSE

Purpose of this task is to allow to use and display sponsors on an Event front
page without using tracks. Moreover online and chat capabilities should be
part of a sponsor feature, located within website_event_exhibitor module.

SPECIFICATIONS

Move everything related to event.sponsor model from website_event_track
to website_event_exhibitor. Functionally feature should be the same as
before except that we should be able to configure and display sponsors
directly with website_event_exhibitor application without using tracks.

Website_event_exhibitor should also define the sponsor template used to
display sponsors below an event.

Merge website_event_track_exhibitor into website_event_exhibitor and remove
dependency on website_event_track. That way all features related to sponsors
are now located within website_event_exhibitor

SPECIFICATIONS: CSS

Purpose of this commit is simply to try to reorganize css currently split across
two files without any real clear difference between those files. We now
have 3 files: a common for all event-related webpages, a file for event list
view (displaying events in frontend) and event page view (display a specific
event details in frontend).

Sponsor specific CSS is moved into website_event_exhibitor so that it contains
its own specific CSS

SPECIFICATIONS: SPONSOR MANAGEMENT

Introduce a new category field containing sponsor, exhibitor or online
exhibitor. Meaning is

  * sponsor: display as a sponsor (sponsor cards at the bottom of events).
    No publish management is done at sponsor level: a sponsor is always
    displayed in the sponsor widget;
  * exhibitor: display as a sponsor in sponsor cards. An exhibitor is also
    displayed in /exhibitors page and allow publish management. Also allow
    to edit description as it is used in front-end page view of exhibitor;
  * online exhibitor: same as exhibitor and allow to configure jitsi (online)
    capabilities. It also activates display of jitsi in frontend;

An exhibitor would be a sponsor that has a physical stand but no online
support. Online exhibitors hold a jitsi room to chat with online visitors.
Also add field in kanban view.

In frontend rename "Connect" to "More info" when exhibitor has no online
capabilities. That way we don't connect with an exhibitor that has only
a published description.

SPECIFIATIONS: B2B

Clearly separate sponsorship levels (gold, silver) from exhibitor type
(sponsor, exhibitor, online). Propagate this new naming through views and
menus as well as frontend filters.

Reword sponsor form view, notably to have a clean 2 column display. Left
column holds customer related information. Right column holds event and
sponsorship information.

SPECIFICATIONS: FIXES

Apply various fixes

  * fix unpublished badge on exhibitor cards;
  * fix display of sponsor content when image overflows;
  * improve display sidebar flag / description columns in page view;
  * show opening hours in exhibitor frontend page;
