JEditorPane need to support "charset" in the <META> tag of HTML.

Version 4.01 is supporting "charset" attribute which parse the encode
like a description below.
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
                                                    ^^^^^^^^^^^^^^^^^^^^
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
  ^^^^^^^^^^^^^^^^^
<meta http-equiv="Content-Type" content="text/html; charset=ISO-2022-JP">
  ^^^^^^^^^^^^^^^^^

If open the html file which includes charset above with JEditorPane in Merlin,
JEditorPane ignore "charset" attribute due to HTML version 3.2.

e.g.) If set "charset=shift_jis" in meta tag and html source character code is
 encoded shift_jis, it does not display correctly on solaris eucjp locale due
 to encode is not parsed with JEditorPane.
