Update Balinese to use two scripts

Balinese was using the Balinese script here. Actual modern usage
is mostly in the Latin script, and so it is in translatewiki and
in the Incubator. The Balinese script is only used in particular
situations and quotations.

The Balinese script version is added as a separate entry, similarly
to Javanese, the real-life usage of which is similar.

This was requested by the Balinese translatewiki and Incubator editors.
