"Create New" button has wrong behavior

[jdalbey]

On the Incident Palette window (accessed from "Load Incidents" menu) there is a button "Create New". Currently clicking this causes the Incident Editor window to appear for a new incident (that has the next sequential event number). This doesn't work ideally because it doesn't display the Incident Properties window. (Also, if by coincidence the Incident Editor is closed with no events added, the Properties can't be opened until an event is added.)

The desired behavior is clicking "Create New" should behave exactly as the "New Incident" menu item: displaying the Incident Properties window.

Also, 3 related modifications:

1. Change the button label to "Create New Incident".
2. The Incident Palette window needs a title, "Incident Palette".
3. There is an unlabeled text input field at the top of the form (that was intended to be for a search filter) that is no longer needed and should be removed.

Fixed in r189 and r190.
