Fixes to twitter examples
Add gtk.FileChooserButton()
Add FileChooserButtonWithDialog

And fix some panics due to GtkResponseType.
Fix EventKey for tip
New functions to work with Pixbufs: PixbufFromFileAtSize(path string, imgW int, imgH int) (pixbuf *GdkPixbuf, err **glib.Error) GetFileInfo (path string, imgW *int, imgH *int) *GdkPixbufFormat
gtk: Added widget RadioMenuItem with some functions gtk_radio_menu_item_new : RadioMenuItem(group *glib.SList) *GtkRadioMenuItem gtk_radio_menu_item_new_with_label : RadioMenuItemWithLabel(group *glib.SList, label string) *GtkRadioMenuItem gtk_radio_menu_item_set_group : *GtkRadioMenuItem.SetGroup(group *glib.SList) { gtk_radio_menu_item_get_group : *GtkRadioMenuItem.GetGroup() *glib.SList
merged patch: https://github.com/sqp/go-gtk/commit/704d779f397570bb409f2169c0dec1d3b43fd0ff.patch
gtk: added FileChooserButton and FileChooserWidget: gtk_file_chooser_button_new : FileChooserButton(title string, file_chooser_action GtkFileChooserAction) *GtkFileChooserButton gtk_file_chooser_widget_new : FileChooserWidget(file_chooser_action GtkFileChooserAction) *GtkFileChooserWidget
glib: *CallbackContext.Args() : Now return type CallbackArg, alias for uintptr. CallbackArg comes with the method ToString() to convert the returned argument into a usable format without having to call the reflect and C packages. +Added method: *GValue.GetBool() bool
GtkTreeViewColumn : Now have the related GObject as anonymous field. Allow to use the SetProperty method.
*GtkTreeModel.GetIter() : Fixed a bug with the TreePath. Call to unsafe.Pointer seemed useless here.
*GObject.Connect() now return the go callback id as an int to use with the new signal control methods. The behaviour is similar to the handler id returned by GTK. The only difference is that the returned int is the go-gtk callback function id. + *GObject new methods: HandlerBlock, HandlerUnblock and HandlerDisconnect all use the call_id int as only argument. + *GtkWidget new methods: needed to get access to those functions until GtkWidget has a Gobject field. HandlerBlock, HandlerUnblock and HandlerDisconnect (same parameters).
GtkTextBuffer : Now have the related GObject as anonymous field. Gives direct access to signal handlers methods.
