Support viewing all posts on a blog with a specific language.
Blog authors should be able to have e.g. both an English and Spanish home page.
- Authors should be able to e.g. set a logo for each language
- Verbiage for standard elements should be presented in the correct language
Similar to when viewing hashtags, filter posts by stored language on this URL: e.g. /lang:es where es is the language code.
The page should look exactly like the standard blog index page, but only containing the filtered posts.
