Port from libglade to GtkBuilder

Here a patch to port the tests to GtkBuilder.
I've not tested the patch but I think should work.

For info about migration take a look here: http://live.gnome.org/GnomeGoals/RemoveLibGladeUseGtkBuilder and here: http://library.gnome.org/devel/gtk/unstable/gtk-migrating-GtkBuilder.html

    configure: Require GTK+ >= 2.12 for GtkBuilder
    
    GTK+ 2.12 is already older than 2 years so this shouldn't
    be a problem for anybody. Also it's only used in examples.

i didn't look into these two commit, but i'm able to build gst-plugins-bad on rhel/centos-5 with glib-2.20.5 and with gtk2-2.10.4 which is older then the above GTK+ 2.12! 
the only thing i recognize is this line during the configure:
------------------------
configure: using GStreamer Base Plug-ins in /usr/lib/gstreamer-0.10                                                                                                                                            
configure: Using GStreamer Base Plugins in /usr/lib/gstreamer-0.10                                                                                                                                             
checking for GTK... no                                                                                                                                                                                         
checking for GMODULE_EXPORT... yes
------------------------
so imho it'd have to somehow fixed.
anyway the only reason for all current version ie:
gstreamer-0.10.28
gstreamer-plugins-base-0.10.28
gstreamer-plugins-good-0.10.21
gstreamer-plugins-bad-0.10.18
gstreamer-plugins-ugly-0.10.14
is gst-camera which is require GTK+ >= 2.12. for everything else gtk2-2.10.4 is enough. so imho it's really questionable to fix this bug or leave it as it's now . since currently it can be build without GTK+ >= 2.12.

Levente Farkas: I am not sure I understand what you are asking for / arguing.

If you have a too-old Gtk+, the gst-camera example will not be built, but it is still possible to build the rest of gst-plugins-bad of course. The bug has already been fixed. It was the right thing to do. Why do you say 'it is questionable to fix this bug or leave it as it's now'?

i said that the commit's changelog said
configure: Require GTK+ >= 2.12 for GtkBuilder
which is not true. it's just check whether gtk+ > 2.12 and if yes then build gst-camera otherwise don't.
imho it's good behaviors and not do not force anyone to use gtk+ > 2.12.

Ok, so the commit message is a bit misleading, since it is a soft requirement only, but we can't change the commit message now in retrospect. Gtk+ should be an optional dependency here, I think we agree on that. So were you just nitpicking about the commit message, or is there anything wrong with our build setup and there are problems when buildling against older Gtk+ versions?

no everything else is ok.
