Allow setting color for abnormal characters in editor from skin file

[ArtemKuchin]

in editdraw.c

/* If non-printable - use black background */
color = (style & MOD_ABNORMAL) != 0 ? 0 : p->style >> 16;

So, if, for example, file contains CR (^{M) i see a lot of} M on black background tearing apart all my nice colors and poking my eyes out.
It would be nice to have something like editabnormal in skin file to set it to something noticeable but nice.

I tried adding it myself

skin.h

#define EDITOR_ABNORMAL_COLOR     mc_skin_color__cache[50]
#define MC_SKIN_COLOR_CACHE_COUNT 68
and renumbered cache array

colors.c

EDITOR_ABNORMAL_COLOR = mc_skin_color_get ("editor", "editabnormal");

editdraw.c

        else
            //tty_setcolor (EDITOR_ABNORMAL_COLOR);
            tty_lowlevel_setcolor (color);

But it does not work somehow. Compiles fine but just does not work. Abnormal chars just show as normal.
