Remove `arguments.caller` and `arguments.callee`

arguments.caller and arguments.called have been deprecated.

They make code optimizations difficult and their use is forbidden in ECMAScript 5 while in strict mode.

Apply with the Grit CLI

grit apply no_caller

Remove arguments.callee

BEFORE

function factorial(n) {
  return n == 1 ? 1 : n * arguments.callee(n - 1);

}

BEFORE

function whoCalled() {
  if (arguments.caller == null) alert("Call from the global scope.");
  else alert(arguments.caller + " call me!");
}

AFTER

function whoCalled() {
