GTK 2.x deprecated functions

Hummm, there was a bunch of deprecated functions all over the code and
that was a *real* pain to fix it...

I've added the missing flags (*DISABLE_DEPRECATED) so I could find the
offending calls, and changed the Makefile.am while I was at it, then I
carefully fixed the deprecated calls.

I've removed xfdiff4 from the compile process (read the xfdiff4 subdir
is not in the configure script anymore) because this one is really
totally deprecated (it calls old gdk_font_* stuff) Someone will have to
take care of this one, but right now, I'm too tired!

The rest seems to be fixed anyway... It's big changes, so I wouldn't be
surprised if some problems arise due to my modifications.

Take care,
