Added e-printable.c and e-printable.h.

2000-06-10  Christopher James Lahey  <clahey@helixcode.com>

	* Makefile.am: Added e-printable.c and e-printable.h.

	* e-printable.c, e-printable.h: This new class is a printing
	context.  Other classes return an EPrintable which represents a
	context for printing that object.

	* e-util.c, e-util.h: Added
	e_marshal_NONE__OBJECT_DOUBLE_DOUBLE_BOOL and
	e_marshal_DOUBLE__OBJECT_DOUBLE_DOUBLE.
