Re-Evaluate iOS support

[Darkhax]

After reading a few blog posts on the libGDX site I think it may be a good idea to look into iOS support once again. They currently provide two back ends for iOS. The first is Intel's Multi-OS engine, and the second is MobiDevelop's RoboVM fork which is not discontinued.

This is definitely a good enhancement, but there are two issues:

• It requires a Mac
• It requires an iPhone or iPad

I'd be happy if someone could contribute that to me.

Although we could use a VM!
