Enable translated database strings the right way:

Enable translated database strings the right way:
  * Use the primary key of the given table, in combination with class hint
    and property, to identify the translated string
  * Stuff the primary key into the PO comment field so we can round-trip it
  * Adjust the oils_i18n_gettext() function to accept the additional parameters,
    including both INT and TEXT primary keys
  * Adjust the database seed values to use explicit primary keys throughout,
    and adjust the use of oils_i18n_gettext() to pass the additiona parameters
