Abuse filter management

This filter is intended to capture new pages created by anonymous users which tend to be vandalism or test edits.

* Initially, targeted to the namespace 0 only.

* fmt and strict comparison

* cover all non-talk-pages except categories, timed text and deletion requests

* For reference, see [[Special:Permalink/85313982#Proposed Change of Rules]]

* Even if it hurts me and Commons, I am going to activate this filter because it turned out that >99% of the tracked edits were indeed trash;  

* Discussion is now available at https://commons.wikimedia.org/wiki/Commons:Administrators'_noticeboard/Archive_39#Proposed_Change_of_Rules ; for namespaces it is active on-- see filter conditions

* Allow creating CfDs (Category for discussion)

* When making changes to this filter, please update [[Module:Editnotice]] accordingly

* extra parentheses added, == instead of === (no idea what is wrong)

* sandbox per false positive report

/* simple conditions that aren't met by many actions first */
