Change Spanish login/logout translations
Right now Spanish translation (es.yml) uses Conexión and Desconexión as translations for Login and Logout respectively.
Unfortunately that confuses many users, because Conexión is exactly the word for Connection, and Desconexión means Disconnection.
These words don't really describe what the links do, so my suggestion is to use alternate translations that reflect the real meaning of login/logout.
I have attached a patch to modify those translations on trunk.
