When a new language is added, pre-populate the translation of various option value

When installing CiviCRM, option values and some other string are initialized in the database using sql files.

If later on, we add a new language or change the default language, the database translation will not be updated because there is currently no sql files to update.

We can't assume that people install English first, so we can't just send strings in ts() and update the database based on the .mo files.

An option would be to move option-values from xml/templates/civicrm_data.tpl to an XML file, and then do lookups in the XML file using the option_value.name.
