Merge checker-2570-2

Authors: mesozoic, therve
Reviewers: glyph, exarkun
Fixes #2570

Add the possibility to twistd plugins to use cred checkers, via
twisted.cred.strcred.AuthOptionMixin?. This allows twistd plugins to accept
checker via command-line arguments, and also offer a way to create other
pluggable checkers. The only plugin modified for now is the words one.
