CSS lang pseudo-class is not honored

[GoogleCodeExporter]

Flying Saucer, when generating PDF files, does not honor the lang pseudo-class.

Given the following html snippet, Flying Saucer only displays the font color as 
blue. It should be displayed as red.

Example:
...
<meta http-equiv="Content-Language" content="ja-JP" />
<style type="text/css">
body {
  font-family: sans-serif;
  color: blue;
}
body:lang(en-US) {
  color: green;
}
body:lang(ja-JP) {
  color: red;
}
</style>
...

The :lang pseudo-class is already parsed by CSSParser and added to the internal 
selector representation.  The language to use for a particular element is 
determined by the NamespaceHandler (NamespaceHandler#getLang(element).  
Currently the default implementation just consults the lang attribute on the 
element itself.

The NamespaceHandler implementation to use can be customized by the user so 
improving this wouldn't require any changes to FS proper.  Improvements here 
that can be incorporated back into the default implementation would definitely 
be appreciated though.

To those with the same issue. A patch has been supplied and I believe been 
merged into the stream.
