Added opts.modalPlacement to change modal class
Added .wide class for modals

This will give us a double-width modal for complex data editing (such
as the class editing modal with instructor calendar).
No idea what we used these for????

Commented out this styling for now until I can figure out what it was
used for.  I know it was on the selectize elements, but can’t remember
what it’s purpose was.
Added additional calendar stylings
Split class edit into two-pane wide modal

Also added functional instructor calendar
Fixed FullCalendar binding issues, added modal calendar

There was an issue with how the events were being updated that should
be good now, overwriting the array of arrays was the issue, instead,
just overwrite the first array with new data to update the FullCalendar
directive.
