Add a bare-bones EventResultsEditorDialog

This is a dialog because I intend it to be modal--the user should be
unable to interact with the rest of the app while the dialog is open.
Failure to adhere to this could lead to strange behaviors--users opening
multiple EREDs that become out-of-sync for each other, users minimizing
EREDs...
Add a title to ERED
ERED: Mess with some settings

Specifically, make ERED non-resizable and modal (DOCUMENT_MODAL). I'll
set the defaultCloseOperation as I begin to develop the logic.
ERED: Add an actual contentPane
ERED: Add three tabs

As before, added a tabbed pane, three panels, and tab names.

When I implement the logic, I'll make these tabs selectively display
based on the Event. For example, an event without special honors will
not show the Special Honors tab or instantiate any of the logic therein.
