Subject: Remove member `hbox' from `struct _EShellFolderTitleBarPrivate'.
* e-shell-folder-title-bar.c: Remove member `hbox' from `struct
_EShellFolderTitleBarPrivate'.
(make_icon_pixmap): Removed.
(rgb_from_gdk_color): Removed.
(endarken_style): Removed.
(set_style_cb): Removed.
(create_arrow_pixmap): Renamed from `create_icon_pixmap'.
(get_max_clipped_label_width): New helper function.
(size_allocate_icon): New helper function.
(size_allocate_button): New helper function.
(size_allocate_label): New helper function.
(add_icon_widget): New helper function.
(realize): Changed to use `add_icon_widget()'.
(size_allocate): New function, handler for the ::size_allocate
method.
(class_init): Install it.
(e_shell_folder_title_bar_construct): Changed so that the widget
get added to this widget instead of adding an hbox to it and
adding the widgets to the hbox.
(e_shell_folder_title_bar_set_icon): Changed to use
`add_icon_widget()'.
* e-shell-folder-title-bar.h, e-shell-folder-title-bar.c: Changed
to derive from GtkHBox, not GtkEventBox.
