Real fix for trac ticket #140, but not covering all instances of that…

… bug yet. Buttons where the background color is meaningful are now rendered in classic Windows style in the Project Properties and Options menus. (Windows XP style only has bitmaps for button backgrounds.) This bug also occurs on (at least) the vector properties dialog, and fixes for that will be committed later. git-svn-id: http://svn.osgeo.org/qgis/trunk@5871 c8812cc2-4d05-0410-92ff-de0c093fc19c
