* app/gimpbrushhose.c (gimp_brush_hose_load): Fix it. Now the hose
	itself, interpreted as a pixmap brush (which the hose is a
	subclass of), is the first brush in its list. The rest of the
	pixmap brushes in the list are separately allocated ones. Don't
	read the pattern names into dummy buffers, just seek past.

	* app/pixmapbrush.c (pixmapbrush_motion): Now works better, and
	actually steps through the pixmaps in the hose's list. The
	paint_core->brush (which points to a brush hose in the cases we're
	interested in) is temporarily replaced with the current pixmap
	brush to use, and restored after applying the pixmap brush.

	* app/makefile.{cygwin,msc}: Add new files.
