REVISION SUMMARY
  Previously, we assigned a custom system string with a trailing slash
  to wsgirequest.url.
  
  The addition of the trailing slash felt arbitrary and seems to go
  against how things typically work in WSGI.
  
  We also want our URLs to be bytes, not system strings.
  
  And, assigning a custom attribute to wsgirequest felt wrong.
  
  This commit fixes all those things by removing the trailing
  slash from the app path, changing consumers to use that variable
  and to use it without a trailing slash, and removing the custom
  attribute from wsgirequest.
  
  We preserve the trailing slash on {url}. Also, makebreadcrumb
  strips the trailing slash. So no change to it was needed.
