Updated to the unused template report needed

[Gonzom]

Over the past few months there has been work done to the unused template report requirements.

1. Categories which should be excluded should be:

   WHERE cl_to IN (
   'Wikipedia_substituted_templates',
   'Wikipedia_transclusionless_templates',
   'Deprecated_templates_kept_for_historical_reasons',
   'Inactive project pages',
   'Parameter_shared_content_templates',
   'Administrative service award templates',
   'Computer language user templates',
   'Language user templates',
   'Level-zero userbox templates',
   'Wikipedia administrator statistics',
   'Subtemplates of Template RussiaAdmMunRef',
   'Subtemplates of Template RussiaBasicLawRef',
   'New Pages Feed templates'
   )

2. The line "not page_title.endswith('/doc')" should be removed so unused /doc pages will appear. If a /doc page is unused that is usually a sign that something went wrong (sub page of a deleted page, sub page hasn't moved with main page, not needed, etc.).
