+2011-10-11  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/ThemePanel.java: Added
+	  a method fireThemeMoved which is called after a Theme in this panel is
+	  moved.
+
+	* src/main/java/de/intevation/flys/client/client/ui/map/MapThemePanel.java:
+	  Added in internal interface ThemeMovedCallback which might be used to
+	  listen to theme move events. Therefore, MapThemePanel overrides the
+	  fireThemeMoved method and calls onThemeMoved() on ThemeMovedCallback if
+	  it exists.
+

 	* src/main/webapp/FLYS.html: Import OpenLayers 2.11.
