Add types.rdb (formerly known as udkapi.rdb) to MobileLibreOffice

Keeping this stuff working is hard. How did I not notice this before?
I need to make clean more often I guess.

I edited the project.pbxproj file manually as I didn't fully get it
how to set up the wanted handling of this file in the Xcode GUI. So I
just copied the handling of offapi.rdb in project.pbxproj (with
different ids, of course).

I really much prefer doing this fully in Makefiles, as in
CustomTarget_LibreOffice_app.mk.
