* app/Makefile.am: cosmetic change

* app/plug_in.c: reordered #includes to prevent MAX/MIN conflict

* app/menus.c: removed the weird translation code in favor of
the item factory translation function. This may have broken some
.po files.. we'll see. Also, added some more tearoffs and made
tearoffs appear automagically when plugins register menu entries.

* libgimp/gimpimage.c
* libgimp/gimpenums.h: redid the GOrientation enum to match the
app. Removed special casing in the handler.

* plug-ins/guillotine/guillotine.c: small clean up
