The localisation must happen only after loading the list of licenses
from cache so that the name is displayed in the current user's preferred
language, not in the language of the user who initiated the cache
rebuild.
This feature adds an admin tool for creating custom licenses.
Now custom licenses can be added and amended in Moodle, and the site
default can be set to a custom license.
Core licenses remain hard-coded and are uneditable, so they will always
require update within Moodle core updates, and maintain their
internationalisation through core language strings.
This also includes fundamental changes to the license API including
the addition of license caching and deprecation of no longer required
admin settings for license management.
