Show post/comment language

[micahmo]

Pull Request Description

• This PR adds the ability to show the post language in the post metadata. If the language is Undetermined, nothing is displayed (matching the web UI).
• There is also the ability to see the post/comment and languages in the bottom sheet (and we could possibly extend this area to include more metadata in the future, so people can see more info about posts/comments without cluttering up the default view).

I think this looks good! Just a quick UI comment - for the language metadata in the bottom sheets, can we make it so that the background is transparent, rather than the dark grey?

I feel like the dark grey background brings a bit too much attention to the metadata. Let me know your thoughts!

Of course! I simplified the bottom sheet to use the same LanguagePostCardMetaData as the post listing itself. Let me know if this looks good.

LGTM!
