[java-gnome-hackers] Update to GTK+ 2.18

[Guillaume M. <res...@gm...>]

Hi,

Many of you have probably seen that GNOME 2.30 is out. With this new
release, comes a new version of GTK+ which is GTK+ 2.20.

Before adding coverage for GTK+ 2.20, I tried to update the .defs files
to be able to use some new things from GTK+ 2.18. I used the .defs files
from pygtk to update ours.

I also added coverage for the GtkInfoBar widget (which is new in GTK+
2.18) and made an example so show how it works.

The branch can be found at 'hackers/guillaume/gtk-2.18'. Let me know if
something can be improved (I'm not used to update .defs files, I may
have forgot something[s]).

Cheers,
