User:Monkbot/task 16: remove replace deprecated dead-url params

The new version of the Module:Citation/CS1 suite deprecates dead-url and deadurl because these two parameters violate the nominal standard that says that parameters ending in  hold a url as a value.

The purpose of task 16 is to replace various combinations of dead-url and deadurl and their associated keywords with url-status and its appropriate keywords.

description
dead-url and deadurl accept a limited set of keywords that control the rendering of cs1|2 citation templates that have archive urls. The keywords that concern this task are:

the remaining keywords, retain their meaning and purpose:

Because no and yes (and the other 'positive' keywords) are nonsensical,  (replacing  ) and   (replacing  ...) have been assigned to this parameter.

Task 16 searches for templates that use either of the dead-url and deadurl parameters (with or without assigned keyword) and then: dead-url and deadurl without an assigned keyword are intentionally included in this process so that the deprecated, and ultimately unsupported, parameters don't linger in article space.
 * 1) renames the parameter to
 * 2) replaces the assigned keyword  with , and replaces the assigned keywords  ,  , and   with  ; keywords ,  ,   are retained
 * 3) deletes all empty parameters (will delete an empty url-status parameter when archive-url is present and has a value)

edit summaries
Task 16 writes an edit summary message that tallies the number of replacements and the number of deletions. The message has the form:
 * replaced (n×) / removed (n×) deprecated |dead-url= and |deadurl= with |url-status=;

the edit summary has a link to this page.

ancillary tasks
Deletes all empty parameters from templates that are repaired.

This task does not do awb general fixes.
