Fix compilation and address some warningsexternals/muse

Replace remaining uses of `cl` with `cl-lib`.
Activate `lexical-binding` in the files we touch.
Adjust code accordingly (especially uses of `add-to-list` applied
to local variables).
Sync README with the one from github.
Adjust to the move to `lisp` subdirectory.
