bad UI defaults

[Dave Love]

I haven't used the current codebase much, but there are several user
interface things in the head code that have been changed to what I
think are bad defaults.

 * The `mode-line-inactive' face is bright compared with `mode-line',
   and different to the menu bar and scroll bar colours.  That means
   that with two windows -- my most common configuration -- the eye is
   drawn to the wrong window.

 * The changed behaviour of the blinking cursor -- solid and empty
   box, rather than solid and absent -- makes it hard to read the
   character under the cursor, at least with the font I use
   (lucidatypewriter-medium-*-normal-*-*-120).

 * The smaller (one-pixel?) width of the outlines of boxes and arrows
   in the menus means they pretty well fade away on my 1280×1024
   display.  It's not clear whether or how you can revert that.  [For
   some reason, the menu bar face is also different from what I see in
   21.2 with the same X resources, but I don't know why.]

 * The new mode-line order is worse IMO.  Also it's hard for the less
   sophisticated to revert to what they're used to, since it's not
   customizable in an accessible way.  To me the time, mail status and
   battery status are important and shouldn't be shunted off the
   right.  I don't care about the line number and people who worry
   about line numbers usually aren't using Emacs properly.  I may be
   in the minority, but I'd expect that to be the case also for a lot
   of users who'd have more trouble changing it.  I think there should
   at least be some Custom option to allow you to reorder the normal
   elements of the mode line.
