[guide-user] Web site update

Hi folks,

Regarding the deep-sky problems: Guide does shut off the "extended"
deep-sky catalogues when you get to level 5 or above. The main goal
here was decluttering/evading having the screen slow down to a halt.

A while back, I added the feature (for user-added datasets) of
specifying the fields of view at which a given dataset would be shown,
so you could say that "dataset X has so many objects that it should be
shown only if the field of view is zero to 10 degrees". I have hopes
of extending this to other datasets, so that a sufficiently determined
citizen _could_ (for example) turn galaxies "on" and see all of them
at a 180-degree field of view. It might be a mess... but you could _do_ it.

Ronny Martens pointed out a few blatantly strange large cities. The
problem with these was that they were indeed in the list, but their
"level of importance" was _very_ wrong. I have fixed this. To see it,
you'll have to get the new geographic name file:

I got these names from a variety of sources. The "level of interest"
data is of somewhat variable quality... most of the names came from the
Bureau des Longitudes, which had "Londres" for "London" and "Hanovre"
for "Hannover". I've fixed most of these, but I'm sure I've not gotten
them all yet.

There is, unfortunately, not much I can do about Fiji (or a few
other places where the geographic data is odd). This data came from
the "World Data Bank" database, and I don't have tools for editing it.
Fortunately, the nearest Guide user is about 1300 km away from there,
in New Caledonia (see map at
