	* Evolution-ShellComponent.idl: add a "debug" method to tell a
	component to output debugging messages to a given file.

	* main.c (main): Add a "--debug filename" argument, to direct
	debugging output for all components to a file. Redirect the
	shell's stdout/stderr to that file if this argument is used.

	* evolution-shell-component-client.c
	(evolution_shell_component_client_set_owner): If debug_log is set,
	call the component's debug method as well.

	* evolution-shell-component.c (impl_ShellComponent_debug):
	redirect stdout/stderr to the named file and emit a "debug"
	signal.
