Screen Bounds changes in iOS 8

I had an error rotating my app, and after read some
articles like this:
https://github.com/openframeworks/openFrameworks/issues/3158

and this:

s-size-becoming-orientation-dependent-in-ios8

it seems that iOS changes the way it calculates and present the
UIScreen bounds, so I needed to remove a bit of code to make it IOS8
compatible.
