This PR addresses :

• Missing ARIA label in NavBasic
• Removing Italian entry from Language Dropdown (it was there to test fallback funcitonality)

• Remove unused imports regarding 18n in some files.

@andrewn Can you have a look at this, please? Conflicts have been solved and it's up to date.

@oruburos When I load my user's assets page (http://localhost:8000/andrewn/assets), I see a blank screen.

The Web Inspector's console tab shows the following error:

Uncaught TypeError: this.props.t is not a function
AssetList.jsx:89

Can you take a look please?

Great work!

@catarak there is work to do to have a complete translation, specifically the issues mentioned in #1584 and #1587, but I think that in the current state is helpful.

@catarak My feeling is that we can turn this on and address the two other issues soon.

Makes sense to me! I think it's okay to have the translation mostly done and to start getting feedback from users.
