Crummy Server REPL

Code:

var stdin
var repl = function() {
  file.load('/server-script/stdin.js', function(contents) {
    if (contents != stdin) {
      stdin = contents
      console.log(eval(stdin))
    }
  })
}
setInterval(repl, 1000)

Edit the listed file (stdin.js), and hit save instead of return.

Note that you only get access to symbols for the file it's in - so in main.js you won't be able to see the global `armies` in playing.js
