Update rules.txt with changes.txt

[Kgx Pnqvhm]

In the \docs directory, the rules.txt file needs to have the changes from changes.txt factored in. E.g., he new JtR compatible memory rules.
And the wiki page kept in sync, too.
E.g., are those "Implemented specific functions" all hashcat only, or is "@X" the only one?
The documentation on the reject rules is hard to find.
