A new menu feature "Refresh license database" is now available from the top context menu.
Its action is to parse all the .rif files under ux0:licence/app and ux0:licence/addcont,
and import them to the ux0:licence/license.db SQLite database (which gets created it it
doesn't already exists).
Used in conjunction with the new App/DLC refresh feature, this allows Vita users to
restore their content straight from PKG downloads, and let VitaShell do the job of also
restoring the relevant license from the DB backup.
This also fixes a small typo in LANGUAGE_CONTAINER_SIZE and adds a .editorconfig, to
ensure that the indentation settings of VitaShell are followed by modern code editors.
