[TYPO3-content-rendering] spam protection and @media speech

[Martin Kutschker]

Hi!

The current code without any TS settings has this output:

user(at)domain.tld

Does any of these markups improve the usabilty for screen readers

@media speech, aural {
   .silent { display: none }
}

user<span class="silent">(</span>at<span cass="silent">)</span>domain.tld

user<span class="silent">(</span><span title="@">at</span><span cass="silent">)</span>domain.tld

user<span title="@" class="silent">(at)</span>domain.tld
