Warn about invalid translations

broken:

n-comments: '{numComments, plural, =1 {1 comment} andere {# comments}}'

fixed:

n-comments: '{numComments, plural, =1 {1 comment} other {# comments}}'

it would have been cool if ember-intl could’ve warned me about the broken plural rule. instead sentry.io was reporting “infinite rendering invalidations” and apparently the user interface for the users using that translation was repeated several times (see https://github.com/skylines-project/skylines/issues/615).

I’ll have to think about it. Might be a good idea, yeah. What I’m a little worried about is having a mismatch between the CLDR versions and not being able to resolve cldr-core properly.

Woohoo 😃

Do you think it’s worth pulling this work into a stand-alone addon, when you’re ready, into something like ember-intl-icu-linter? This can be a future task, just bike shedding on how we can scale this to add additional linting (i.e., key collision detection).
