Issue #1483672 by russellb: Tidy up variables made by multi vocab code on uninstall

  variable_del('taxonomy_nco_minimum_match_intersection');

  variable_del('taxonomy_nco_analysis_last_update');

  variable_del('taxonomy_nco_last_cron');

  // tidy up multi variables

  // TODO: upgrade this so that is only deletes variables made by this module, not the

  // whole taxonomy_nco variable namespace

  // TODO: separate uninstall for taxonomy_nco and taxonomy_nco_anaylsis

  db_delete('variable')

    ->condition('name', "taxonomy_nco%", "LIKE")

    ->execute();  

  /*

   *  from issue #1483672

   * 

   *    Here are the "multi" variable we use:

   *    taxonomy_nco'.$multi_id.'_include_tags_in_related

   *	taxonomy_nco'.$multi_id.'_minimum_match_intersection

   *	taxonomy_nco'.$multi_id.'_default_minimum_match_nco

   *	taxonomy_nco_block'.$multi_id.'_vocabularies

   *		

   *	so something like

   *	if (preg_match('/^taxonomy_nco(_block(_\d+)?_vocabularies|(_\d+)?_(include_tags_in_related|minimum_match_intersection|default_minimum_match_nco))$/',$varname)) variable_del($varname);

   *    in the loop, could do the trick in a safe way.

   *		

   *	PS: and maybe a loop on the $conf keys is better than a db select...
