Wiss update event

PR for help

There are 2 fixme in EventEditForm.jsx

First one, I'm not being able to retrieve the id that is passed from Events.jsx (in the tablesorter)

Second one, I can't retrieve from the backend the event. The call is made, and if I try outputting in the backend the event, it works, I just can't pass it to the frontend... Halp

well createEvent doesn't expect an id. You have to create a new route with a different component that has the path `/event/:id`
