Updated translations from Transifex

Fixes bug #1175241

This is a grizzly version of commit b7e36244c0
in master branch. To avoid fuzzy strings PO files are directly downloaded
from Transifex instead of cherry-picking from master.
This commit does not override the source language 'en'
to avoid the bug fixed by commit a7505869c4.

Increase socket timeout for selenium tests

I can reproduce bug 1100771 consistently in my development environment.
Increasing the socket timeout in the SeleniumTestCase class fixes
the timeout issue for me.

This uncovers another issue that causes an "Address already in use
error". This happens because the order of tear down is wrong - we
need to quit() the driver before continuing with tear down rather
than after.

Fixes bug 1100771.

Mark additional strings as translatable

Some variables and templates variables that should be translatable
weren't marked as such.

Fixes bug #1180316

Note the change in horizon/templates/horizon/common/_quota_summary.html
is not backported in this commit to keep the existing translations work.
