Feature: 'Previously generated-password-negation', not drawing from raw tried list but a token-type

[JBoekhout]

Capturing and negating more futile passwords in the starting try-compilation

[JBoekhout]

Syntax suggestion: cat tokens.txt: -i (with i = previous attempt tokenset index) token-item j -> for each token-item in i . . . ###'broad' token-set which gets negated by previous, probaly, more, focussed attempts. This feature helps OOM failed-to-computes like #199 gets at.
