Sitebase locale

This covers sitebase and no_auth_sitebase, which manages the nav bar, etc. 

For some reason, the inclusion of the templating on the nav bar results in it no longer doing the sub menus (the mouse over type) but instead just expanding the sub menus. I don't know how to debug without more knowledge of css and these things...
Can you open an issue please? Since this is in support of internationalization anyway, it may just not make sense to even have these links
