* Changes to the encoding mechanism. If iconv is found, it is used first

for encoding changes.  This should be the case on all 1.8 installations.
  When it isn't found (<1.6), the native REXML encoding mechanism is used.
  This cleaned out some files, and tightened up the code a bit; and iconv
  should be faster than the pure Ruby code.
* Changed deprecated assert_not_nil to assert throughout the tests.
* Parse exceptions are a little more verbose, and extend RuntimeError.
* Bug fixes to XPathParser
* The Light API is still shifting, like the sands of the desert.
* Fixed a new Ruby 1.8.0 warning, added some speed optimizations, and
  tightened error reporting in the base parser
