[TIMOB-2611] iOS: className and classNames unsupported

Assigning to Steve to start looking at this or alternately discuss and delegate the R&D to Blain.

Need a description of what these features are and how they work in Android because all that comes up on google is refs to Titanium.

From Marshall, who implemented this for Android:

• You can assign 1 or many classes on your view object by using the className or classNames properties:

   var view = Ti.UI.createView({
     className: "myClass",
     classNames: ["myClass1", "myClass2"]
   });
   

• In addition to whatever classes you apply to your view, it also has it's API name lowercased as a class name (this was originally the only class name that was used)
• IDs are no long required for JSS stylesheets to be applied, the stylesheet logic will apply to any view that matches classes or the ID
• You can programmatically add a class or classes to a view. Right now this just applies the class properties directly on top of the view. At some point we'll need to implement a better browser-style property inheritance. Example:

   view.addClass("myClass1" [, "myClass2"..]);
   

To get started, you basically just need to create a ".jss" file that matches the js file you need styles for. For example, to use styles in app.js, you'd create a file called app.jss. To support medium density specific styles, create "...jss", in other words: app.android.medium.jss or app.android.high.jss

(from [af9e7fbbb60e9fcce19dea99b3707be199499e18]) [#2611 state:fixed-in-qa] Changes to recognize className on iOS. Special thanks to Marshall for doing almost all the work for me. https://github.com/appcelerator/titanium_mobile/commit/af9e7fbbb60e9fcce19dea99b3707be199499e18"> https://github.com/appcelerator/titanium_mobile/commit/af9e7fbbb60e...

To test this bug:

• Output in KS should match a pull from before the commit which fixed this bug. app.js and app.jss have been changed to use a classname for win1 instead of id.
