Comment notifications are sent in the sender's language setting

[ayleph]

When a user comments on a media entry, the notification email sent to the recipient is sent in the sender's language locale, not the recipient's.

Does mediagoblin even have the concept of a user's language besides what the current request passes? As best as I can tell it doesn't. Perhaps mediagoblin should add a configurable user setting for preferred language, defaulting to whatever header they passed when they created an account.

I can't think of a better way. Maybe we could add a migration to extend the LocalUser class as below and then query the user's locale_preference when sending email to that user. CCing tsyesika for input.

I think adding a locale preference option on the user model is an excellent idea. This should also be configurable in the UI I think (but default to whatever the browser tells us upon joining).

Thanks for the input Tsyesika. At this point you're much more familiar with the user model than I am, so getting your approval makes it sound like a workable idea. I'll try to start working on some code changes to incorporate a locale preference and add UI configuration options. Eventually we'll need a migration as well.

It looks like this is a duplicate of #504. However, since the original ticket has almost no discussion, I'm going to close it in favor of this one.

Also, it appears that the idea of adding a language preference previously appeared in #247, so I've double-duplicated tickets. However, since both of these tickets have useful comments about how to address the issue, I don't want to close either one yet.
