added prompt function

Prompt for user input with optional message.
Returns a string.

Example:
var ask = console.prompt("Whatsup ?");
var name = console.prompt("Please enter your name:");
did var io =...
fixed up prompt()

Fixed up, and cleaned up. Re-tested, works.
Letting non-strings be passed in for 'promptStr', so variables or other values can be used.
Look good ?
Any further suggestions ?

@tach4n good idea for the getline wrapper

Thanks you two..
