EventForm: view / edit functionality

[klequis]

When user navigates from MyEvents to a given event, it should be view mode

When user clicks on the edit button form should switch to edit mode.

Implementation

• A form for Edit
• A component for view

The form for Edit already exists 'EditForm'

The view component does not exist. It should be called EventDetails and live in its own folder under src/ui

EventDetails will

• get the event data from redux using from redux state.eventsUi.edit_id which is set when a user clicks on an event in MyEvents
• render the picture and all other event data in a easy to read layout
