[AC-1950] Mobile Web-specific code doesn't get used

Problem

Building for MobileWeb doesn't use the mobileweb specific files which are located in the mobileweb directory /Resources /Logic db.js /mobileweb /Logic db.js

Test case

1. Create new Titanium Project with template "Single Window Application" 2. Create a db.js file in /Resources/ with content:

exports.initializeDB = function() {'use strict';
	return 'Standard DB Initialized';
};

3. Create db.js file in /Resources/mobileweb/ with content:

exports.initializeDB = function() {'use strict';
	return 'MobileWeb DB Initialized';
};

4. Use this file somewhere for UI

var db = require('/db');
var label = Ti.UI.createLabel({
		color:'#000000',
		text:db.initializeDB(),
		height:'auto',
		width:'auto'
	});

5. Build for iOS and see text 'Standard DB Initialized' 6. Build for MobileWeb and see same text instead of 'MobileWeb DB Initialized'
