Only create the GaugeTree and RiverInfoPanel once

This fixes resizing issues when changing the river. SmartGWT is not able to
recalculate the height and width if a GWT widget is inserted later. Every
attempt to call a recalculation manually did fail.

Fix for flys/issue925 (W-INFO / Pegel-Info-Modul / Zeile Gewässer-INFOS)
