enlightenment revamp, part III (trunk only)

Replace the old ^X output with integrated enlightenment feedback.
Expands enlightenment output into four sections:  Background and
Characteristics in addtion to previous Status and Attributes.  Final
disclosure and ^X in wizard or explore modes show all four; potion/wand
of enlightenment and throne insight show the last two to give traditional
enlightenment, near enough; and ^X in normal mode shows the first three,
encompassing the 3.4.x ^X display in streamlined form plus providing
details about bottom line information.

     I think I'm done with enlightenment for the time being, except for
the desire to move it (plus associated conduct feedback) to end.c or
perhaps its own file.  It has grown very long and doesn't particularly
fit in cmd.c; I don't think it ever belonged there at all unless wizard
mode ^X predates potion of enlightenment.
