Jehan 0974920bdd Issue #22: Hebrew CP862 support.
Added in both visual and logical order since Wikipedia says:

> Hebrew text encoded using code page 862 was usually stored in visual
> order; nevertheless, a few DOS applications, notably a word processor
> named EinsteinWriter, stored Hebrew in logical order.

I am not using the nsHebrewProber wrapper (nameProber) for this new
support, because I am really unsure this is of any use. Our statistical
code based on letter and sequence usage should be more than enough to
detect both variants of Hebrew encoding already, and my testing show
that so far (with pretty outstanding score on actual Hebrew tests while
all the other probers return bad scores). This will have to be studied a
bit more later and maybe the whole nsHebrewProber might be deleted, even
for Windows-1255 charset.

I'm also cleaning a bit nsSBCSGroupProber::nsSBCSGroupProber() code by
incrementing a single index, instead of maintaining the indexes by hand
(otherwise each time we add probers in the middle, to keep them
logically gathered by languages, we have to manually increment dozens of
following probers).
