[Zope3-checkins] SVN: Zope3/trunk/src/zope/app/publisher/browser/ Fix obscure case of files without extensions in resource directories.

[Fred L. Drake, Jr.]

Log message for revision 26941:
  Fix obscure case of files without extensions in resource directories.
  
  Files with names that matched the extensions being checked for could
  have the wrong kind of resource created for them; imparticular, files
  named simply "png" or "gif" (a really weird case) would have image
  resources created for them rather than simple file resources.  Fixed,
  added a test case.
  
  Use a instance of object for the marker value, since that's a simpler,
  immutable object with a smaller memory requirement.
