	Bug 520078 – Rotate brushes

	Applied patch from Alexia Death:

	* app/core/gimpbrush.[ch]
	* app/core/gimpbrushgenerated.c
	* app/core/gimpbrush-transform.[ch]: affine transformations for
	brushes. So far only scaling and rotation is supported. The
	transformation is done using nearest-neighbour. This is a
	regression and we need to add back interpolation before the next
	release.

	* app/paint/gimpsmudge.c
	* app/paint/gimppaintoptions.[ch]
	* app/paint/gimpbrushcore.[ch]: allow to control the brush
	rotation angle.

	* app/tools/gimppaintoptions-gui.c
	* app/tools/gimpbrushtool.c: added UI for controlling the
	brush rotation angle.

	* app/actions/tools-actions.c
	* app/actions/tools-commands.[ch]: add actions for controlling 
the
	brush rotation angle.
