* Fixed some bugs with the SelectionListeners and the JMapPane. To make this work,  StyledFeatureLayerSelectionModel now extends StyledLayerSelectionModel<String>. So the selection is remembered as a Set of Feature-IDs. This change was needed, because Feature.java doesn't overwrite the equals method, and therefore the HashSet didn't function as expected.
* Added new Tools and BUttons to MapPaneToolBar.java to select features
* Changed a lot in MapPaneToolBar.java. It now allows to position Spaces, Actions and Tools via the ID field. (the new feature is to mix them)
* Fixed a bug in AV's ClickInfoPanel that would suddenly pop up an AtlasViewer if started from Geopublisher under special circumstances.
* Moving layers in the legend is using MapContext's move method instead of remove and insert.
* LayerPanel's remember* Maps now all have the MapLayer's ID as a key. 

This commit includes latest schmitzm.jar and av.jar. The av.jar is also commited to the ISDSS, but the ISDSS will still have the old schmitzm.jar. Latest schmitzm.jar in ISDSS should be updated ASAP. I just don't know where to put it.
