Fix event wizard date picker (remove dependency)

Use plain html functionality instead of bootsrap datepicker.
Remove datepicker dependency.
This resolves #200 (datepicker not loading since load from CDN is blocked by CSP).
Improve how form media is loaded in event wizard.
Additionally, improve which fields are shown (and how) in event wizard.
