+	flys/issue323 (Datenkorb: Doppelklick im Datenkorb sollte gewähltes Thema (Themen) laden)
+
+	* src/main/java/de/intevation/flys/client/client/event/DatacageDoubleClickHandler.java:
+	  New. Interface for double click handlers used in the datacage.
+
+	* src/main/java/de/intevation/flys/client/client/ui/DatacageWindow.java:
+	  Implements the DatacageDoubleClickHandler. After a doubleClick event has
+	  been received, the selected Themes from datacage widget are loaded and
+	  the window is destroyed.
+
+	* src/main/java/de/intevation/flys/client/client/ui/DatacageWidget.java:
+	  A double click on a tree node triggers the onDoubleClick method for each
+	  registered DatacageDoubleClickHandler. A DatacageDoubleClickHandler
+	  may register itself via DatacageWidget.addDatacageDoubleClickHander()
+	  method.
