	* src/file.c (cb_select): New callback: Make double click on list
	in import filter chooser works like "OK".
	(workbook_import): Back when we first started using glade, we used
	a hack to avoid flicker when popping up the filter chooser. We now
	know how to do it right, and remove the hack.
	(workbook_import): Connect callback to handle double click.
	(workbook_import): Fix bug: return value from import would clobber
	return value from dialog_run. We now close dialog after retrieving
	selection, but before importing.  We really should keep the dialog
	up until user either succeeds with import or explicitly
	cancels. But we let that wait. This behaviour should be
	implemented in a lot of places in a coordinated way.
	(workbook_import): Do not destroy workbook after WM close - it is
	already destroyed.
