Avoid unnecessary page reloads by using javascript

[arborrow]

When viewing a retreat (which we may want to start referring to as events - which might include renaming the controller to EventController if we want to be consistent about sticking to the table names although the word event has a special meaning in Laravel - https://laravel.com/docs/5.7/events - so maybe retreats is just as good of a word as any other) - in any case - retreat show blade loads with a list of all the registered retreatants with pushbuttons to change statuses for when they arrive, depart, etc. Currently, clicking on one of these buttons reloads the entire page and it would be much nicer if this was handled by javascript and the necessary section was updated.

There may be other areas as well that could benefit from having some js to keep things efficient.
