NASL2: precedence of 'logical NOT'

First I forgot to put '!' in the list of %prec instruction.
Then I added it, but probably in the wrong place.
_Currently_, things like ! x == y are parsed as (!x) == y, which is
wrong IMHO. It should be ! (x == y)

Worse "! x >< y" is parsed as "(!x) >< y" which is absurd.

So, the priority of NOT should be set _below_ the priority of the
compare operators.
Where exactly? Below AND and OR? Or not?
i.e. "! x && y" = "! (x && y)" or "(!x) && y" ?
I vote for the 2nd interpretation.
