Support all languages in SMS interface

Maybe put "Search PERSON_NAME" etc. to .po file and either manually or automatically import the translation. Currently we need code change to add support for each language.

Random thought: if we did this, I think we might have to let admins specify which languages to support for SMS for each repo. Otherwise, matching against so many possible translations could risk misinterpreting input. For example:

• If someone was searching for "Ben Jackson" but didn't know you had to say "Search" at the beginning of the message (i.e., they sent an SMS just saying "Ben Jackson"), it would be interpreted as Turkish for "I am Jackson" and add a new record indicating someone named Jackson was alive.
• If a Swedish, Norwegian, or Danish user was trying to search for someone but made a typo, they could end up sending "soy X" (one letter off), which is Spanish for "I am X", causing a record to be added with the exact name they were searching for.

That's good point. We already have a list of primary languages per repository, configurable in the repository admin page. Maybe we should only enable only those languages.

Other things to consider:

• Which language should we use for the "help message" we provide when the input is invalid? Maybe only the top language, or in all primary languages?
• Another challenge is multibyte characters. From what I heard a few years ago, SMS network in the world is not always multibyte safe. We currently have logic to remove diacritics for European languages, but that won't work for Japanese, Chinese, etc.
