Make LispSyntax JupyterKernel

[MasonProtter]

To make this nicer for people to use, I think it'd be cool to make a special jupyter kernel that just parses a code block with the lisp parser before being sent to the regular julia jupyter kernel.

Just like in #28, this would be nice since users wouldn't have to use the string macro directly and could have custom syntax highlighting / indentation rules.

I'd be interested in working on this sometime in the next couple of months.

cool. If you get something, I'd happily merge.
