Improve the MapWindow Toolstrip


The MapWindow toolstrip needs to be improved. Here are some missing features:
1) Add a Zoom Out button and a Zoom Out map function
2) When the Zoom In, Zoom Out, Identifier, Pan or Select button is clicked, it should stay highlighted until the user clicks another toolstrip button
3) Add a custom ZoomIn, ZoomOut, Pan and Select cursor like in MapWindow 4
4) The ZoomIn, ZoomOut, Zoom to Full Extent and Select buttons should only be enabled when there are some layers displayed in the map.
5) The 'Pan' cursor and toolstrip button need to be made consistent.
5) The Attribute Table button should only be enabled when a layer is selected in the legend.
