	* app/main.c
	* app/appenv.h: moved "message_handler" from here...

	* app/core/gimp.[ch]: ...to here. Added gimp_message() and a
	"gui_message_func" pointer...

	* app/gui/gui.c: ...which gets set here to gui_message().

	* app/errors.c: don't include any gui stuff but simply call
	gimp_message().

	* app/app_procs.c: don't set "message_handler" here, it's done in
	gui.c now.

	* app/gui/error-console-dialog.[ch]: use gimp->message_handler.

	* app/gui/dialogs-constructors.c: pass a Gimp pointer to
	error_console_create().

	* app/widgets/gimpwidgets-utils.[ch]: made the "message" parameter
	of gimp_message_box() a const gchar*, not just gchar*.

	* tools/pdbgen/pdb/message.pdb: use gimp->message_handler, don't
	include "appenv.h".

	* app/pdb/message_cmds.c: regenerated.

	* app/devices.[ch]: cleanup before chopping: removed global
	variable "current_device", added devices_get_current(), pass lots
	of Gimp pointers around.

	* app/gimprc.c: pass a Gimp pointer to devices_rc_update().

	* app/display/gimpdisplayshell-callbacks.c
	* app/gui/toolbox.c
	* app/tools/gimppainttool.c: use devices_get_current(), pass Gimp
	pointers to all devices_foo() functions.

	* app/core/gimpimage-mask.c: no need to include "pdb/pdb-types.h".
