Gnats 6071: Expression Slot Evaluation Range fields not resized correctly 
 for different font size.

This commit has geometry fixes in two related dialogs:

(1) The Open Series Expression Slot dialog's Evaluation Time config data 
panel was clipping the Evaluation Range text.  The dialog width now grows 
to accommodate the full text.  See changes in Q3GUI/SlotQtDlg.

(2) The "Configure Timeseries - Evaluation Range" dialog had many geometry 
problems in the Qt Designer created UI file which showed up especially when 
changing the size of the RiverWare font.  See changes in Q3GUI/
ExprSlotTimeRangeDlgWidgets.ui.
