Typo in uninstall SQL

In mapi.install, the following block includes a typo that causes uninstall to throw an error:

function mapi_uninstall() {
  // wipe ALL mapi related variables
  db_query("DELETE FROM {variables} WHERE name LIKE 'mapi_%s'");

  // remove the programs table.
  db_query("DROP TABLE {mapi_programs}");
}

Should read:

function mapi_uninstall() {
  // wipe ALL mapi related variables
  db_query("DELETE FROM {variable} WHERE name LIKE 'mapi_%s'");

  // remove the programs table.
  db_query("DROP TABLE {mapi_programs}");
}

("variable" should be singular, not plural.)
