We already picked the commit that did this change, so no idea why it is gone.

    and other changes were not necessary.

Redirect to user preferred language page from the home page

If there are no matching languages, the project listing page is displayed.

(The templates haven't been removed since the home page will be reworked
sooner than later)

Pick notes: Just solved the conflicts raised because of code divergence. Now
    the code is exactly the same.

Conflicts:
	pootle/apps/pootle_app/views/index/index.py
Removed unused stuff
Cleanup: removed unused table fields

Pick note: Minor conflicts because of the priority column for goals we have.

Conflicts:
	pootle/templates/browser/_table.html
Partial pick: Cleanup: removed a bunch of dead code

Pick notes: Most of the changes were already performed. get_translate_actions
    is kept to allow displaying the translate action for the next goal.
    This will eventually be moved to the place where the other translate
    actions are created.
