- Ignore the query string when checking if a link's status has changed. This should fix many of the reports about dismissed links re-appearing for (apparently) no good reason. This is particularly important for redirects where the order of query parameters might change, or an affiliate site might add random tracking codes to the redirect (some just add a random number; probably to bypass caches). 

  - Add a note to the per-link log when the plugin un-dismisses a link because its status has changed. This helps figure why a link is no longer dismissed when you dismissed it an think it hasn't changed. 
  
  - Store the full final URL in the result_hash instead of just a MD5 has. It's easier to detect problems if you can see what the URL was. Long URLs might get truncated due to the field size limit, so reconsider this if someone reports problems.
