Improve locale command

I would like to suggest some improvements regarding this part.

1. Adding an extra parameter to command "/bentobox locale" when using the command "/bentobox locale", adding an extra parameter [all/active] would be useful. "All" means detect discrepancies for all languages while "active" means only detect for the language currently in use. The rationale is that other languages that I am not using is not useful to have them checked for any discrepancy between that and default language. Another reason is that currently most of the locale files are not up-to-date which results in a very spammy console, considering some addons may be installed as well.
2. Export to text file When there are multiple addons installed, the console would become extremely spammy and hard to extract or trace any useful data. An option to export the result into a file or simply direct extraction would be useful. If it is to be extracted, the console could be just showing how many files had been detected with discrepancy(ies) found.

Feel free to let me know if you need any further elaborations on the above. Happy Lantern Festival!
