Improved Castable models. Moved EO metadata utility functions to own module. Added inline documentation:
Updated WMS URL. Removed Metadata collapsed state.
Improved interfaces for connectors, style applicators and layer factories. The first two now do not need to pass the cache instance, as this is now handled globally. The latter one allows more than one suffix for each layer factory.
Adapted new interface.
Adapted interface for various WMS renderers. The available suffixes are now provided by the renderers themselves.
Adapted new interface.
