+	  flys/issue22 (Abgelaufene Projekte/Collections werden noch in der Projektliste angezeigt.)
+
+	* src/main/java/de/intevation/flys/client/client/Config.java,
+	  src/main/java/de/intevation/flys/client/client/config.xml:
+	  Added a config option to specify the update interval of the project
+	  list. This value is retrievable using the method
+	  Config.getProjectListUpdateInterval().
+
+	* src/main/java/de/intevation/flys/client/client/ui/ProjectList.java:
+	  Added a timer to update the user's collections frequently. The interval
+	  is determined by the constant UPDATE_INTERVAL which is currently 30
+	  seconds or a config.xml option that needs to be configured at
+	  "/config/projectlist/update-interval/text()".
