Title: Add option to use repl with color,and show help about option. And Fix various bug I find.

- When "require('./prettyPrint')",don't work in my Ubuntu. Fix lower strings ("./prettyprint").
- Using only ":s" in Repl,show "Undefined is undefined" Message.Fix show "Usage :s Command" when only ":s" was used.and add ":s" help message.
- with "-c" or "--color" option,repl shows messages with color.
- with "-h" option, show help about option.
