[beast] DOCS: Create html/ directory whenever we write to it.

    DOCS: Create html/ directory whenever we write to it.
    
    This patch was created because a user reported that Makefile rules seemed to be
    executed in a different order, so that
    
      cp ./imports/beastdocs.css ... html/
    
    failed.
