Fix, attributedStringConsumer

[Georg Fleischmann]

here is a patch for GSRTFcolorfg() to allow parsing of RTF streams created on  
OpenStep.
OpenStep doesn't add a color list to rtf streams, if the color is just black.  
The attached patch simply sets the color to black, if the color index is out of 
 
bounds.
