With this commit, it is possible to load the web client in a language
different than the user by using the `lang=` query string in the url:
For example, `/web?lang=en_US`
This is useful when we need to quickly check something, without changing
the current user settings. Note that it will only work if the url lang
has been installed on the database (if lang does not exist, it will fall
back to en_us).
