[IMP] website_event(_track)_online: improve registration flow

RATIONALE

Events are sometimes held online, gathering a community. In this merge we
improve Event application to better support full-online events with improved
tracks, wishlists, chat rooms, .

PURPOSE

Improve the overall registration flow. In addition to already improved features
(email, standard pages), some improvements are done here specifically for
Online feature.

SPECIFICATIONS: REGISTER MENU

Add a register button to the right that can be removed through an option on
the event itself. Currently register menu is lost within other event menus.
In this commit we add a CTA to the right lf event naviguation in order to show
it to customers. If current user has registered this button is not displayed.

This is done in addition to already existing register menu. This one can be
tweaked through frontend menu edition. CTA has another purpose, bringing
people to register through a visible CTA.

SPECIFICATIONS: REGISTRATION CONFIMATION

At the end of registration process, add a link to the talks. It allows to
send people directly to the talk page in order to complete their wishlist.

SPECIFICATIONS: IS PARTICIPATING

Make "is participating" field functionally working for public users. It is now
computed based on visitor. If a visitor is available check its registrations
in order to determine if current user has registered to the event.

Remove support of 'email' based computation of "is participating" as this is
quite unsafe: partner and visitor should give results interesting enough.h.
