It can be useful to have similar class messages grouped together so that
error messages in a larger report don't get lost among the
warning/info/action messages.
This patch allows sorting of messages for dialogs that benefit from
organization. Default behavior of reporter messages remains
unchanged by this patch.

Also fixes:
- forcing the annotation scope to "full schematic" when run
as a prerequisite to Generate Netlist.
- a long-standing bug where displaying extra items in a dialog
would mess up the height of the HTML_REPORT_PANEL (becasue
we were setting the html window's height rather than its
parent flexgrid.
- initializing the annotation radio buttons to safe values
(full schematic and keep existing)
