[Bug-wget] adding --filename-exclude-url-query

[bugged buggy]

   i was in a situation where the website generates different access token
   for the same file during each refresh , which was specified in the url
   query , so wget wasn't detecting that the files already exists ,
   causing tons of duplications each with different url query
