Proposal add support for latin American preferred language
Currently when editing the preferred language for a contact we have these 3 spanish options
Our standard appears to be the IETF language tag https://en.wikipedia.org/wiki/Language_code
However, we don't offer es-419 "Spanish appropriate for the Latin America and Caribbean region, using the UN M.49 region code"
This ommission is not just at the option value level - but at the schema level. In order to support this language variant we need to alter the schema to accept 6 rather than 5 characters for the preferred_language field
<field> <name>preferred_language</name> <title>Preferred Language</title> <type>varchar</type> <length>5</length>
