Sven Neumann 28fddfd554 Makefile.am removed this header file. 
2003-03-25  Sven Neumann  <sven@gimp.org>

	* Makefile.am
	* gimpintl.h: removed this header file.

	* gimpmiscui.c: include libgimp-intl.h.

	* gimp.c (gimp_main): call setlocale() and bind to the libgimp
	textdomain so that plug-ins don't need to do that explicitely.

	* libgimp/stdplugins-intl.h: added the functionality that used to
	live in gimpintl.h and removed the libgimp related stuff. Got rid
	of the INIT_I18N_UI() macro.

	* plug-ins/*/*.c: removed all occurances of INIT_I18N_UI().
	Plug-ins simply call INIT_I18N() once in their run() function.

	* plug-ins/script-fu/script-fu-intl.h: added the functionality
	that used to live in gimpintl.h and removed the libgimp related
	stuff.

	* app/Makefile.am
	* app/gimp-intl.h: new file that defines the gettext macros for
	the GIMP core.

	* app/*/*.c: include gimp-intl.h instead of libgimp/gimpintl.h.

	* plug-ins/script-fu/scripts/test-sphere.scm: fixed typos.
