Added Foreground Coloring to Fields Based on Query

Per a customer request, we have modified orprerender.cpp to color a field on a report based on a query.  The code will look for the color in <column>_qtforegroundrole (as in the xtreewidget) and, if found, apply that color to the fields displaying <column>.  The only color column presently implemented follows the <column>_qtforegroundrole naming convention.  We have not implemented background colors or the coloring of entire rows in the printed report.
