+++ This bug was initially created as a clone of Bug #5645 +++

Description: The user signature button needs to be disabled when a user is
editing articles in the main section of Wikipedia (i.e. pages that are intended
to be articles). This problem leads to user confusion and an unnecessary user
signature in articles. Further, this will prevent the need for clean up of
articles with Special:Cross-name space page.

See bug 5645 for more info/discussion.

Gerrit change 87649 introduces a new configuration variable $wgShowSigButtonInContentNamespaces. If the change is merged, WikiEditor should also listen to that variable.

I think we need to kill ext.wikiEditor.toolbar.hideSig.js (see bug 40972) and do this some other way - ideally by sending $wgShowSigButtonInContentNamespaces in mw.config somehow.
