[REF] event: allow to use UTMs directly in event

PURPOSE

Allow to use UTMs directly in event, notably to be able to sort or make
statistics on registrations.

SPECIFICATIONS

Move all UTMs fields definition to event. In base event module they are
set by hand or through links (when using mass mailing for example).Shared
links with utm bits defined in it allows to track marketing statistics
on registrations.

In event_sale registrations can be linked to a sale order. UTM information
are copied from the sale order to the registration itself. Order defined utm
always erase default one coming from event.
