Added little XSL tranformation to turn palette XML files into QGIS style definitions.
Useful to display "Horizontalschnitte" in correct colors.

+	* contrib/palette2qgis.xsl: New. XST tranformation to turn a
+	  palette XML file into a style definition suitable to be used
+	  in QGIS. Tested with QGIS 1.4.0-Enceladus. Usage:
+
+	  $ xsltproc contrib/palette2qgis.xsl       \
+	    doc/conf/palette/water-temperature.xml  \
+		> water-temperature.qml
+
+	  Do similar to process salinity.xml et al.
+
+	  When you've loaded the "Horizontalschnitt" polygon layer 
+	  in QGIS, class it via the "CLASS" attribute, load the
+	  according style and apply it. Voila!
