i18n multi-language support

Options for managing translations:

• Crowdin - $19/month for 500 strings or $29/month for 1000 strings (unlimited languages, strings can be as long as you want)
• Transifex - $19/month for a single project, up to 15,000 words (words are literally the number of words in a string, if you have 500 words in English to translate, and translate them into Spanish and German, that goes up to 1500 words (assuming that Spanish and German have the same exact number of words as their English counterparts))
• PhraseApp - $25/month for a single project with up to 20,000 words (same system as above for calculating words), can save money by using year-long subscriptions, they charge for only 10 months of the 12.
• OneSky - Free for unlimited words, up to 5 contributors. Works with i18n Rails, the standard iOS localization strings format, etc.

Crowdin is definitely the best option of the above. It also includes an API for sending new/updated i18n strings to the service automatically as they're added.
