Testcase: Multiple language blocks

This is a testcase to render multiple language blocks on one page.

First: language in the common section

def action_done(self, cr, uid, ids, context=None):
	logger.debug('Overridden mro_order.action_done called.')
	for order in self.browse(cr, uid, ids, context=context):
	    self.pool.get('stock.move').action_done(
		cr, uid, [x.id for x in order.parts_move_lines])
	    self.write(cr, uid, ids, {'state': 'done'})
	return True

Second: language outside common setion, with custom alias (qua.name specific)

(use-package elfeed-org
  :after elfeed
  :init
  (setq rmh-elfeed-org-files (list (concat emacs-directory "feeds.org")))
  (elfeed-org))

Third: language unsupported

Specific test: if there is an unsupported language block, the other blocks should not be affected

require ["fileinto", "envelope", "subaddress"];
if envelope :detail "to" "spam"{
  fileinto "Spam";
}
