This change drops the Lexxy markdown-paste initializer from the initializer bundle. A repo-wide search shows there are no remaining listeners for the "lexxy:insert-markdown" event / "addBlockSpacing", so the previous markdown paste block-spacing behavior is now entirely gone. If that behavior is still desired, reintroduce the handler (or ensure the new Lexxy revision provides an equivalent built-in).
