Avoid dispatch import, revert to simple argument parser

(0.9.2compat) avoid dispatch import, revert to simple argument parser Make nokwcommands a tuple as long as it's private. No need to import fancyopts, as we use own w/o bug. Clean overriding of findcmd. We only need simple argument parsing for command. No expensive dispatch import, also avoids potential clashes with invasive RuleDispatch (setuptools).
