Use a nice terminal for REPL

I found that the REPL was hard to use. Originally I wanted to add this to http://repl.it but found that it needs lots of work for RTL. So I used the [terminal emulator](https://github.com/replit/jq-console).
I also used a [Solarized[(http://ethanschoonover.com/solarized) theme for style.

Additional features:

* Line continuation when:
    * The command doesn't compile; or
    * There is a trailing (. Starts a new line with increased indentation.
    * Holding SHIFT + ENTER.

* Shortcuts:
    * CNTRL + A: Move to beginning of the line, 
    * CNTRL + E: Move to end.
    * CNTRL + C: Discards current line.
* Move between lines of current prompt by holding down shift.
* Paran matching.

Additionally we can add the editor to the left and have a repl.it or (dr.scheme) like configuration.
