Import new version of tor-launcher.

This is the standalone package generated from commit ce81834 on
git://git.tails.boum.org/tor-launcher with the following locales:

    BUNDLE_LOCALES="ar de es fa fr it ko nl pl pt ru tr vi zh-CN"

The master branch has been rebased and now only contain the desired
delta against upstream. Since the last import the only change is that
we fix some "&#160;" (non-breaking space) inconsistencies left from
our fix (a94a6d7) when they were translated incorrectly in upstream.
