Maestro: Auto generate bounds for WMS/WFS based on the items reported spatial context

Before layers can be served as WMS they must have the bounds info applied. Since the bounds info should be in EPSG:4326, it is non-trivial for the user to calculate these.

Since MapGuide exposes coordinate transformation functions, Maestro should be able to convert the boundsing coordinates from the layer/featuresource and create the corresponding EPSG:4326 coordinates.
