#8 Fix build with the latest gnome-panel

[Dmitry Shachnev]

Hi,

I have cloned the latest gnubiff CVS, and ported the GNOME Panel applet from out-of-process to in-process applet. Out-of-process applets no longer work with the GNOME Panel 3.22, see this message for details. I had to refactor Makefile.am a bit, to make this work.

Also, I am attaching another patch with some unrelated build fixes, but I had to apply it to make the build work for me (on latest Debian GNU/Linux sid).

Note: I used spaces for indentation in code in the end of src/ui-applet-gnome.cc, you may want to replace that with tabs.
