Per-script extra keys

Allows to define a locale's script in 'method.xml' and use that to add
the extra keys for a locale to layouts of the same script only.

A locale of an undefined script will add its extra keys to every
layouts. A layout of an undefined script will have the extra keys of all
the enabled locales.
