It should correctly interate on the list of toplevels. In addition, fixed adjust_naming_policy to
avoid a now unnecessary check if this is really a toplevel.

Also fixed some smaller things in the model itself and added support for icons.

...and removed some hacky testing code

There were some checks that are no longer necessary as our project tree is dynamic which
prevented the emission of the "add_widget"-signal.

Actually gtk+ should provide a gtk_tool_item_group_new_with_label_widget() method but
it doesn't and using the construct properties seems broken.

Add an implementation of the GtkTreeModel interface to GladeProject

We already depends on GTK+ 2.20

Added src/glade-close-button.c and removed
plugins/gtk+/glade-cell-renderer-button.c

	  - Stop showing preferences at project new time (now we have tooltips that tell you this stuff),
	    finally closing bug 574095.

	* gladeui/glade-project.c: Display GTK+ in caps and always assume GTK+ as a project dependency
	  (so that empty projects still depend on GTK+ for display purposes).

	  - Added option to show/hide statusbar in the View menu and session data.

	  in the signal editor when doing so.

	* src/Makefile.am, src/glade-close-button.[ch]: Using Paolo Borelli's close button code for notebook
	  tab close buttons.

	* src/glade-window.c:
	  - Added option to disable toolbar in View menu and session data (bug 586194).
	  - Added option to show notebook tabs for open projects also in the View menu and session data.

	* gladeui/glade-palette.c: Made "both" mode use text horizontally again, still get alot of unwanted
	  ellipsize here.

	* gladeui/glade-project.c: Added the targets-changed signal to refresh views with data about
	  target project versions (notebook tabs).

	  asks for an icon at startup.

	* gladeui/glade-signal-editor.c: Fixed access to signal name in object dialog hander (was a crasher).

	* gladeui/glade-widget.c: Fixed GladeWidget to update support warnings on newly added signals.

	* plugins/gtk+/glade-gtk.c, plugins/gtk+/gtk+.xml.in: Block the glade_gtk_text_buffer_changed()
	  handler when updating the buffer text (this feedback loop was causing segfaults when undoing
	  modifications to a text buffer's text).

	* gladeui/glade-popup.c: Allow adding new actions to action groups from the palette ("Add widget here").

	* plugins/gtk+/glade-accels.[ch]: Moved individual accelerator [de]serialization here, special integration
	  for action types, for actions only show one accelerator and dont load/save the "activate" signal name.

	* plugins/gtk+/glade-gtk.c, plugins/gtk+/gtk+.xml.in: Added support for GtkActionGroup <--> GtkAction
	  relationships and support for editing/loading/saving of accelerators which can be associated with
	  actions inside an action group.

	  - Reordered support icon to come before the signal name and let the column be user
	    resizable along with the others (non-resizable unellipzised signal name columns expand over time)

	  - Fixed an assertion and page-size != 0 for adjustment properties in libglade mode

	* gladeui/glade-signal-editor.c:
	  - Dont show swapped column in libglade mode

	  - Give object dialogs a bigger default size and hide the column headers

	* gladeui/glade-signal-editor.c:
	  - Now show an icon and tooltip in rows for signals that are only
	    supported in the future, refresh them when support changes.

	* gladeui/glade-widget-adaptor.h, gladeui/glade-property-class.h: Added some version checking macros.

	* gladeui/glade-signal.[ch]: Add support warning meta data to signals

	* gladeui/glade-project.c:
	  - Simplify code with new version checking macros
	  - Do the verify on signals for widgets as well as project warnings
	    (update the signals a verify time).

	* gladeui/glade-widget.c: GladeWidget takes a new "support-changed" to broadcast support changes
	  on the widget.

	* gladeui/glade-signal-editor.c:
