Set a default language in the preferences for unknown languages

[Gilberto Amaral]

In my case, almost every file that I drag into subler they are english based files but the metadata is set as unkown language. I know id I add the ".eng" in the end of the file the problem is solved and everything inside is imported as english, but it would be nicer and cleanner id I could preset all unkown languages to a default one.

This can be done with the queue. In the future I will make it possible to apply queue presets even in the document window.
