color fix (final!)

[Oskar Liljeblad <oskar osk mine nu>]

This patch fixes a long-standing problem regarding colors in
stable and CVS versions of mc. If your terminal is not listed
in color_terminals (src/slint.c:450), colors won't be enabled
unless you force them with -c. The problem is that mc always
overrides the value of the SLtt_Use_Ansi_Colors variable,
which is already initialized by slang.

Here's a patch to fix it, against the 2002-06-11-11 snapshot.
(With different line numbers it will work against 4.5.55 too.)
I tested it and it works fine (also no compilation warnings).
Please let me know what do you decide to do with it.
