* Rename MkdirOption interface to MkdirOptions It was hard to remember which Options interfaces were spelled in the singular and which in the plural (and anyway this one contained two options). Also added MkdirOptions to cli/js/deno.ts. All the analogous interfaces were exported there. * Rename RemoveOption interface to RemoveOptions This was the last remaining Option interface spelled in the singular. Easier to remember if they're all Option**s**; plus we may want to add extra options here later.
