SqueakGtk status

Here are some news of the SqueakGtk project :

I've extended the Gtk support with new widgets :

• GtkAboutDialog (added some fields)
  
• GtkFontSelectionDialog
• GtkAccelLabel
• GtkLinkButton
• GtkScaleButton
• GtkVolumeButton
• WebKit
• ...

I've corrected a bug with the memory management, it seems that Gtk doesn't like
g_object_unref when there is a parent widget. The support of Gtk
is more stable but there are others problems in the events handling
this is an active waiting so it uses a lot of cpu times, an other problem
is when the user save the image a "Gtk" object in Squeak only contains
a pointer in a C structure and I need to save and restore this structure.

I'm working on the Omnibrowser support and in the improvement of the
new tools :p

Some basic tools :

Squeakzilla a new browser :p
