	* app/Makefile.am
	* app/plug_in.[ch]: removed...

	* app/plug-in/Makefile.am
	* app/plug-in/plug-in-types.h
	* app/plug-in/plug-in.[ch]: ...and added here.

	* app/appenv.h: removed StackTraceMode and MessageHandlerType...

	* libgimpbase/gimpbasetypes.h: ...and added them here.

	* tools/pdbgen/Makefile.am: don't scan "app/apptypes.h" for enums.

	* tools/pdbgen/enumcode.pl: added a general check to prevent
	enums which are defined in libgimp* from being written to
	"libgimp/gimpenums.c".

	* libgimp/gimpenums.h
	* plug-ins/script-fu/script-fu-constants.c
	* tools/pdbgen/enums.pl: regenerated.

	* app/core/core-types.h: include "pdb/pdb-types.h" so including
	"core/core-types.h" gets the whole core type space.

	* app/core/gimp.[ch]: added a "stack_trace_mode" parameter to the
	constructor and store it in the Gimp struct because the value is
	also passed to plug-ins and nobody should include "appenv.h".

	* app/gimprc.[ch]: pass the alternate_system_gimprc and
	alternate_gimprc filenames from the command line to gimprc_prase()
	so we don't need to include "appenv.h".

	* app/batch.[ch]: pass the "batch_cmds" as parameter, don't
	include "append.h".

	* app/app_procs.c: pass more parameters around.

	* app/devices.c
	* app/errors.c

	* tools/pdbgen/pdb/fileops.pdb
	* tools/pdbgen/pdb/help.pdb
	* tools/pdbgen/pdb/message.pdb
	* tools/pdbgen/pdb/plug_in.pdb: changed accordingly:

	- changed "plug-in.h" include where needed.
	- don't call gimp_fatal_error() directly, it's called via the log
	  handler when calling g_error().
	- don't incude "errors.h" except from main.c.
	- changed stack_trace and message_handler enum names.
	- get "stack_trace_mode" from Gimp.
	- removed many inclusions of "appenv.h".

	* app/pdb/fileops_cmds.c
	* app/pdb/help_cmds.c
	* app/pdb/message_cmds.c
	* app/pdb/plug_in_cmds.c
	* app/pdb/procedural_db.c: regenerated.
