[IMP] event: adds graph view and adds change for event_barcode

PURPOSE

- In order to get an overview over events, add a graph view grouped by
event name and measure by seats available.
- Before this commit you had to install event_sale to see the popup window
in the barcode interface when scanning an attendee. With this commit you'll
see the popup even when event_sale is not installed.

SPECIFICATION

- Add the minimal information about the registration in the event module
and overrides it in the event_sale module to add the necessary informations.
That makes the window popup appear everytime when scanning an attendee.
- Add a "is_ongoing" field on event model to use it as a filter in
event_barcode.
