ANNOUNCE: gtkmm and glibmm 2.4.0

*** gtkmm and glibmm 2.4:

gtkmm provides a C++ interface to GTK+. gtkmm 2.4 wraps additional API in GTK+ 2.4. 
gtkmm 2.4 installs in parallel with gtkmm 2.2, so you can have both installed at 
the same time. glibmm is now a separate module, for use in non-GUI software.

gtkmm stays in-sync with GTK+ by following the official GNOME Platform Bindings 
release schedule:

Bindings for the rest of the GNOME Platform are also available, and are also 

*** Changes since gtkmm 2.2:

- Highlights:

  There are several new widgets/classes, with examples:

  * New File Chooser:
    FileChooser, FileChooserWidget, FileChooserDialog, FileFilter classes.

  * Action-based Toolbar/Menu API:
    UIManager, Action, ToggleAction, RadioAction classes.

  * New Combo Box:
    ComboBox, ComboBoxEntry, ComboBoxText, CellLayout classes 

  * Auto-complete for Entry:
    EntryCompletion class.

  * Other new classes:
    IconInfo, IconTheme TargetList.

  * New ATK, Pango, and GDK API wrapped.

- Existing API improved:
  * Use of improved libsigc++ 2 API.
  * Removed useless key-binding signals.
  * Alignment: Added set/get_padding().
  * Entry: Added set/get_alignment().
  * Settings: New properties.
  * ListStore/TreeStores: Added insert_after(), which should be faster than insert().
  * TreeView: Added move_column_to_start()
  * TreeModel: Deriving is now easier, because the virtual functions now use C++ types.
  * TreeModel::iterator: Added operator--(), which is slow.
  * See the NEWS file for detailed API changes.
