Haskell bindings for GObject Introspection, based on the code in http://git.rhydd.org/?p=haskell-gi;a=summary and https://gitorious.org/haskell-gi and some portions of gtk2hs.

This version adds support for:

• Casting between GObject types.
• Conecting callbacks to signals.
• Reference counting for GObjects.
• Automatic conversion between array arguments and Haskell types.
• Proper ownership transfer of function arguments.
• Support for GObject properties using the gtk2hs notation.
• Callback and GClosure arguments.
• Native support for GVariant, GValue and GParamSpec types.

See test/testGtk.hs for a working usage example.
