[SLD] error parsing font paramaters

Hi,

 I wonder what I'm doing wrong here, I'm trying to format the layer's
font with SLD using the <sld:font> tag but if I set the style or weight 
to normal Mapserver ignores everything and use the default bitmap font. 

 I.e., if the following tag is present in the SLD 

  <sld:CssParameter name="font-style">normal</sld:CssParameter>
 
then mapserver will use the default font and ignore the other 
attributes such as size and rotation. This happens with versions 4.4
and 4.6 (ms4w).

  I've build a simple test page to show the problem:
  http://www.cpqd.com.br/mrni-geo/sld_test.html


  Any ideas? From the how-to:

"When a Font Style or a Font Weight is set to normal in an SLD, it is also 
ignored in building the name. For example, if there is an SLD with a Font 
Family of arial, a Font Style of normal and a Font weight equals to bold, 
the resulting MapServer font name is arial-bold."

This was simply not implemented. The documentation was more up to date. I 
think It was just forgotten.

I have added the tests to detect the word normal.
