[TIMOB-12279] MobileWeb: JS files are not copied over if you put them in the mobileweb directory

Problem description

Customers are used to use the "platform" directory for several versions of the same file. I.e., android/samefile.js iphone/samefile.js they know that the right samefile.js will get copied over when compiling. This is failing when you are doing mobileweb/samefile.js since the file samefile.js won't be copied over in the resultant compiled mobileweb.

Steps to reproduce

1. Create new project 2. Copy app.js to app.js in Resources 3. Copy result_iphone.js to Resources/iphone/result.js 4. Copy result_mobileweb.js to Resources/mobileweb/result.js 5. Compile for iphone. You will see a "I'm in the ios version" 6. compile for mobileweb. You will get an error.

Files

App.js

Ti.include('result.js');
var win = Ti.UI.createWindow({
	backgroundColor:'white',
	
});

var label = Ti.UI.createLabel({
	text:text, 
});

win.add(label);
win.open();

result_iphone.js

var text = "I'm in the iOS version";

result_mobileweb.js

var text = "I'm in the mobileweb version";
