Add embedded shell script highlight to vim syntax

This highlights `RUN`, `CMD`, and `ENTRYPOINT` lines using shell highlighting.  It doesn't bother detecting the JSON forms, but that's OK because JSON arrays highlight pretty reasonably with shell highlights. :)

" since @SH will handle "\" as part of the same line automatically, this "just works" for line continuation too, but with the caveat that it will highlight "RUN echo '" followed by a newline as if it were a block because the "'" is shell line continuation... not sure how to fix that just yet (TODO)
