[fdo-dev] GetProviderDatastoreType()

My understanding is that the managed data stores are not mandatory  
and are entirely dependent on the provider. Although webstudio only  
supports sdf and shp providers, they both provide the capability to  
point to an existing data store and this is implemented in webstudio  
as the 'Unmanaged Feature Source' option in the 'File->New' submenu.
