	Applied slightly modified patch from Martin Nordholts which
	implements more fine-grained steps for actions. Fixes bug #165612.

	* app/actions/actions-types.h: add additional values to
	enum GimpActionSelectType.

	* app/actions/actions.[ch] (action_select_value)
	(action_select_property): handle them here and added "small_inc"
	and "delta_factor" parameters.

	* app/actions/context-actions.c: added small and percent actions
	for the brush radius.

	* app/actions/context-commands.c
	* app/actions/layers-commands.c
	* app/actions/tools-commands.c
	* app/actions/view-commands.c: pass small and percent increase
	values to the action_select_foo() functions.

	* app/actions/context-commands.c (context_brush_radius_cmd_callback):
	make sure we don't end up with 1.1, 2.1 etc brush radius values.
