All Events Page

CHANGES:
- Applied database values to Duy's All Events functions and commented
his out for now
- Removed alert in resetInputs()

BUGS:
- New header divs are generated for a course even if one already exists.
- "NO COURSE" shouldn't show up in task container
- Error: Uncaught ReferenceError: sidePanelButtonChange is not defined
(line 1717) when I click on side panel button
- Complete/Edit/Delete functions outdated for this page (needs to
operate like homepage)
- Category icon doesn't set. Need to create a separate function that is
modular for both homepage and all events
- Priority stars don't set. See above
