Allow app.version to be overidden through a command line option
Added option to override view options for layers (to workaround the "international date line" problem.
Front-end handling for layers with view parameters specified.
Completed zoom override workaround.
Fixed broken test.
Fix for #135 When tab is changed to the portalpanel we should update the layer loading spinner.
Problem was that if layer is loaded while the map panel isn't showing then the layerloading message isn't properly hidden.
#135 Actually,call the spinner update directly from the mappanel
Add test for 135, make updateLayerLoading Spinner take a number argument again.
Fixing Styles display for #143
