	* app/config/gimpdisplayconfig.[ch]
	* app/config/gimprc-blurbs.h
	* app/display/display-enums.[ch]: added new gimprc option
	"space-bar-action" and default to "pan". Will add a GUI for this later.

	* app/display/gimpdisplayshell-callbacks.c: respect the new option
	and either pan the display or push the move tool. Fixes bug #349903.
