[web/views] Fix AutoformSectionRelationTags.set_muledit_editable
It is a method call, so `self` is passed implicitely as first
argument, so it is useless to pass it also explicitely as second
argument. In fact, it does not work without this. A monkey patch
had been done in a private client's project, but the fix is
revelant for everyone.
The facets system
-----------------
Facets allow to restrict searches according to some user friendly criterias.
CubicWeb has a builtin `facet`_ system to define restrictions `filters`_ really
as easily as possible.
Here is an exemple of the facets rendering picked from our
http://www.cubicweb.org web site:

Facets will appear on each page presenting more than one entity that may be
filtered according to some known criteria.
