Adjust hidden element rules for printed view
This change updates the hidden element list
for the printed view.
Elements hidden:
* Indicators
* Category links
* Redirect header hidden from all namespaces
Remove selectors that are not inside core. Due to
a miscommunication with Volker these were unintentionally
added in I9aa92a3e70991126c56df0a6db408d1c6f84f172:
* `#coordinates` is added by templates and should be in
MediaWiki:Print.css
* `.play-btn-large` is added by TimedMediaHandler and should
be removed in that extension
* `.noexcerpt` should not be used in this context. It's meant for
marking content up that should be hidden from extracts not for
content that should be hidden from print view - that's what `.noprint`
is for
