	* app/actions/tools-actions.c
	* app/actions/tools-commands.[ch]: added actions and callbacks for
	the new paint options brush scale property. Assigned new
	shortcuts: '<' and '>' are now changing tool-value-1 and '[' and
	']' are changing tool-value-2

	* app/actions/context-actions.c: removed the shortcuts from the
	brush size actions.

	* app/tools/gimpbrushtool.c
	* app/tools/gimpcolortool.c: set tool-value-2 to brush-scale and
	to color-average-radius, so '[' and ']' always affect the size of
	the tip of the active tool. tool-value-1 is connected to
	context-opacity so that is changeable using '<' and '>' now.
