FEAT(client): Allow to overwrite setting's locale

In case you want to use a locale that does not have a corresponding
bundled translation in Mumble, you will probably have a hard time
setting this up in Mumble's settings.

This is important though in case one wants to test a new translation
from an external translation file.

Therefore this commit adds a new command line option that allows
overwriting Mumble's settings manually.
