Magic Constants

Adds some ( yes ) PHP / Python-esque magic constants to the current module. Includes naive tests.

Why???

So you can write a logging function like this, for example:

    var colors = require('colors');
    var format = require('utils').format;
    require('magic-constants')(global);

    function log2(m) {
      var _prefix = colors.green(format('[%s @%d]', caller, __caller_lineno));
      var args = [].slice.call(arguments);
      args.push(_prefix);
      console.log.apply(this, args);
    }

    function main() {
      function bar() {
        log2("Some message", "something else", [1, 2, 3, 4]);
      }
      bar();
      log2("in Main??")
    }
    main();
    log2("in global");
    console.log(__lineno, __function);

I swear, I'm going to go blind printf-debugging node and trying to figure out which log call came from where. This helps me, YMMV.
