Suggested variable naming for top level, local variables, pass-through, added section on loops, async and jsformat settings

Added common practice for loops.
Common practice for handling multiple async calls.
Sublime text2 jsformat suggested settings.
Suggestion on variable naming with reasons.

Example why just using camelCase for variables might be impractical in practice:

/*global define*/
define(function (require) {
  "use strict";

  var _ = require('underscore'),
    BaseSubRouter = require('nagini/subroutes/base'),
    modelCondition = require('nagini/models/condition'); 
    // This can pass jshint check because it is not capitalized
    // where ModelCondition will ensure that people do model = new ModelCondition({});
    // so jshint will do the checking for classes which require "new" to be used.
    
   return BaseSubRouter.extend({
      list: function (topic, id, anchor) {
         var modelCondition;
      // Issue 2: When referring or creating modelCondition the usual practice
      // is to do modelCondition = new ModelCondition({})
      // However we now are confusing with modelCondition declared at the top.
      // If  we use lowercase
      // var modelcondition
      // modelcondition = new modelCondition({});
      // this is easier to differentiate 

      this.slideRight(modelCondition);

    },
    slideRight: function (modelCondition) {
      // Also same issue here for passthrough variables.
      // pass-through variables and local variables differentiation 
      // between the camelCase top level variables

    }
  });
});
