Bug 893144 - /newsletter/existing/ styling

The styling sheet on /newsletter/existing ws messed up - the
descriptions were all bolded and the newsletter titles were small.

Reverted styling of the TH part of the table to what it was in an
earlier version of newsletter.less. No way to tell what happened
to it due to rebasing on the original branch.

Bug 892696 - Change default language for /newsletter

On /newsletter and footer email forms, if the user's locale is not
for a language that our newsletters support, then instead of
defaulting the language field to 'en', default to having it not
set, to force the user to choose one of the supported languages
when subscribing instead of just clicking through and maybe not
wanting English but getting it anyway.
Bug 893165 - /id/newsletter formatting

The issue was that in the header 'Read all about it in our
<span>newsletter</span>', the <span> and </span> each were causing a
line break. In languages like Indonesian where the word order was
changed, e.g.:

    Baca selengkapnya di <span>nawala</span> kami

this was breaking the header up into three short lines.

It turned out that header spans were being styled in newsletter.less
as "display: block". Getting rid of that solves the problem.
