some rules missing in readme

[ghost]

unbound-method and assertion-type are in code and missing in documentation
other rules may be missing too

[veritem]

both rules are still a work in progress, that is why they're not shown in the docs. I'm going to keep this issue open to track when I'll get time to fix them.
