AJAX spellchecker #29

This is nearly a complete rewrite of the gmail like AJAX spellchecker
from http://www.broken-notebook.com/spell_checker/index.php

Here are the differences and features

  * seemless integrated into DokuWiki
  * no need for the pspell extension
  * needs GNU aspell installed (not sure about the version I guess
    0.60+ for UTF8)
  * needs PHP 4.3.0+
  * uses SACK for AJAX
  * gets errors and suggestions in one transfer

So far only tested in Firefox. It should work in IE, Safari and
Opera 8, too. Please test and report back.
