deleteScript should be private

I am not aware of a valid use for deleteScript. It should be removed from the public class interface.

I disagree, we use it to unload the script on language change and load it back in with a new language.

FWIW, the API does not officially support doing that.

Once the maps API is starting to use WebComponents (currently in beta), it will no longer be possible to reload the Maps JavaScript API. See also my comment here: #100 (comment). Hence, there will no longer be support for this in the next major-release of the api-loader.
