Log:
Big thandy installation refactoring. Things should be saner now: we recognize that checking an item is sometimes orthogonal to installing it; we do not carry around big bits of unimplemented machinery; we actually document what stuff does in thandy-spec.txt; we do more OO in the places that make sense and less in the places that do not; and almost as an afterthought, we support the command installer type internally. Now all we need is a frontend to make command installers.
