[web/views] Stop mishandling the fieldset name in the default form renderer While not really documented, it is generally assumed that: * the fieldset is a user-visible string (much like a title), * it will be translated by whichever piece of code uses it. So: * fix AutomaticEntityForm to generate untranslated fieldset names, * fix FormRenderer to properly translate the fieldset name before rendering it, * stop using the field set (which may contain whitespace) as a CSS class name (the feature was unusable, so just drop it), * properly handle the colon as part of the translated fieldset name Closes #4881298

RSS driven
----------

RSS is a pretty useful technology that can be widely used on this
site. Any set of data can be presented as RSS. You can then plug in
an RSS reader into that and follow the site activity. For example :

:raw-html:`<p><a class="reference"
href="view?vid=rss&amp;rql=Any+X%2CM+WHERE+X+modification_date+M+ORDERBY+M+DESC+LIMIT+30"><img
alt="rss" src="data/rss.png"> latest changes</a></p>`
