Implement i18n

[misterupkeep]

Big and painful one (maybe). See: nuxt i18n module

Seems to like to do i18n by generating locale-specific routes. Our layouts stay the same though (maybe not for arabic? we could do rtl props everywhere; let's wait to blow up in the muslim world first before worrying about that though -- and let's not even think about all those vertical writing systems, sorry that you get shafted).

But it should also provide a good old locale string database

Most Asian languages were vertical but that's obviously not practical enough to have survived as the primary direction. It's also worth noting that both Discord and Element have no support for Arabic.
