event create/edit

some outstanding issues:

- remove default action for form submit when click on buttons like upload images/menu
- having spaces in file picker image names=dealbreaker?
- hook up add to calendar on event show
- existing event time doesn't show up in drop down on edit form for event
- event edit - input vs. display from database not same format for time...need to think a bit about best way to resolve this when person changes time on edit form
- images
- menu
