How many languages can this support?

[carcinocron]

This component looks good for the 1-10 languages range, but is it intended to work/scale with 20-50 languages?

When some one does choose a new language, is that an http call or is the second language simply part of the minified javascript app?

I'm running it in production with 3 languages, each having approx. 1000 keys. I can't say whether it scales beyond 10 languages. All languages' translations are currently sent to the client at once.

Does it support date formats or digit grouping symbols by default? Or are these rules are something I have to declare on my language file?
Thanks

Counterpart (used by this component) supports localizing dates (see https://github.com/martinandert/counterpart#localization). PR's welcome!
