	Finished the addition of "gboolean reverse" to the gradient API:

	* tools/pdbgen/pdb/gradients.pdb: added "reverse" params to
	gimp_gradients_sample_uniform(), sample_custom() and
	get_gradient_data().

	* app/pdb/gradients_cmds.c
	* libgimp/gimpgradients_pdb.[ch]: regenerated.

	* libgimp/gimpgradientmenu.c: changed accordingly.

	Made everything compile with the new API:

	* plug-ins/FractalExplorer/Dialogs.c
	* plug-ins/FractalExplorer/FractalExplorer.[ch]: got lost in
	"reverse" adding, whitespace removal and general code cleanup.
	I better commit this now before continuing, even though "reverse"
	adding is not finished.

	* plug-ins/common/sample_colorize.c: removed own gradient
	reversing code, use "reverse" instead.

	* plug-ins/common/gradmap.c
	* plug-ins/flame/flame.c
	* plug-ins/gflare/gflare.c
	* plug-ins/pagecurl/pagecurl.c: simply pass reverse == FALSE and
	added #warnings that more work needs to be done. Some whitespace
	removal and minor cleanup.
