CE-876 New dashboard widgets (more or less):

- New Composite & Block widget constructs.
- Option for a parent widget's label to be the app home page's label
- Updates to table-widget handling of fixed footer (to expand and stay fixed)
- Option for widgets to have CSV Data that can be exported differently from just the data "in" the widget.
-- This included changing the default value for showExportButton from true to false
