* Added the lower-case Shift-JIS files to the manifest. The upper-case ones

  should be deprecated, but I need a Shift-JIS encoded XML file to test
  against, first.
* Added support for maintaining external entity occurances in DTDs
* Deprecated the use of Document::DECLARATION.  The new default declaration
  can be gotten with XMLDecl::default()
* Refactored the encoding support code.  It should be more robust now,
  and fixes a few bugs.
* The XPath string() function now deals with Element nodes properly.
* Serialization with Output objects now works as would be expected.
* Various code cleanups, some reducing the number of warnings that Ruby 1.8.x
  produces with REXML.
