	* shell/e-shell-view.h: New private field in EShellView added,
	which contains the notebook and a hashtable of folders to views.

	* shell/e-shell-view.c (e_shell_view_set_view): Instead of
	creating a new control every time we set the view, we now keep our
	controls in a notebook. This function now switches to the correct
	notebook page, or creates a new page/control as necessary.
	(e_shell_view_new): Creates and inserts the notebook into the
	shell.
