[facets] Correctly look for inputs of type "hidden" (closes #4502768) jQuery ':hidden' selector looks at CSS visual properties (eg, 'display', 'visibility'). The intent here was probably to look for inputs of type "hidden", which many facets use to store user selection data (eg, FacetRangeWidget). The problem is that regular text inputs (eg the "has_text" facet which has a '<input type="text"/>') will be picked up by this selector if they are inside a folded facet. Chaos and destruction ensue.

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>`
