iOS Prep & Platform Update

Updated LibGDX Libraries to latest 0.9.9 vs. This added RoboVM support.
I added RoboVM libraries which will hopefully allow us to compile the
Java code into objective-C code for iOS.

Further, platforms are now created using platform spawners that adjust
to the dilation of the speed of the world. Ceiling blocks were created,
although no additional functionality were added to then.
