1. base: Load translation when language is activated
Purpose
------
Settings > Translations > Languages > I find the language I want
and I click on stat button to activate it.
Now I set it up on my user, it still doesn't work > the langage has not been loaded !!!
Specification
-------
When activating a language load the translation (and open the load translation wizard)
2. base: Add shortcut button to load language
Pupose
-------
On the res.partner and res.user form view if you want to change
the language, it's not easy to know where I can activate more
langages.
Specification
-----------
Add a small icon next to the language field to activate more
languages (similar interface than to send an SMS).
3. base: Clean res.lang tree view
1. Set limit to 200 to display all current 82 languages
in one page (current limit is 80/82).
2. Move some fields to debug mode.
3. Add a button to directly load a language.
4. base: Remove Load a Translation menu
Activating a language automatically load the translation,
hence the menu is no longer necessary.
5. base: Don't show language if only one active
If only one language is active, don't show in the contact
form view (`res.partner`) the language field. Changing the language is
not possible since there is only one language.
Hence the field is useless and therefore hidden.
