[ALOY-377] Touch Test - An Alloy enabled app won't work by default because there isn't an app.js by default

When I was testing if Soasta Touch Test would work with an alloy project, I discovered that by default it won't because when you touch enable the app it looks to add code to app.js which won't be there. Steps to reproduce: *You will need access to Touch Test to reproduce this issue* But generally the process is 1. Create a new default Titanium mobile project 2. Allot enable it 3. Follow the instructions contained here for touch test enabling a Titanium app: http://cdn.soasta.com/productresource/download/SOASTA_TouchTest_Appcelerator_iOS_Tutorial.pdf Actual result: You will notice in the docs that touch test enabling an app adds code to app.js. This is why by default the app won't be touch test enabled. However, if you copy and paste the following code in index.js the app will then be touch test enabled

if (Ti.Platform.osname === 'iphone' || Ti.Platform.osname === 'ipad')
{
  var touchTestModule = require("com.soasta.touchtest");
  var cloudTestURL = Ti.App.getArguments().url;
  if (cloudTestURL != null)
  {
    // The URL will be null if we don't launch through TouchTest.
    touchTestModule.initTouchTest(cloudTestURL);
  }

  Ti.App.addEventListener('resumed',function(e)
  {
    // Hook the resumed from background
    var cloudTestURL = Ti.App.getArguments().url;
    if (cloudTestURL != null)
    {
      touchTestModule.initTouchTest(cloudTestURL);
    }
  });
 }

Expected result: We probably need to work with Soasta to detect whether an app has an app.js or an index.js to put the code into.
