	Added loading of Photoshop brushes. Fixes bug #163047:

	* app/core/Makefile.am
	* app/core/gimpbrush-load.[ch]: new files holding all brush
	loading code. Added .abr loader based on a patch by Adrian
	Likins. Didn't add a new brush subclass as in the original patch,
	but only a loading function which loads the brushes into standard
	GimpBrush objects. Did misc fixes to the code, needs further
	cleanup.

	* app/core/gimpbrush.[ch]: removed brush loading code here.

	* app/core/gimpbrushpipe.c: changed #includes accordingly.

	* app/core/gimp.c (gimp_real_initialize): register the new load
	functions and their extensions with the brush factory.
