Lack of relationship for .pbz and .pbl file

[aoshimak]

On latest Android app, it seems to lack the setting of relationship for the files that have extension ".pbl" and "pbz". If this relationship is not affected on Android system, it is very hard to install additional, non-official language pack, and firmware update. If the problem comes from this application, please re-add this function or re-add extension relationship for Android systems.
