Modifications to: 1) centroid display, animations when hiding / showing, web view transparency, web view close icon, web view borders. Additional behavior to allow for "fake" responses from server. A hack somewhere that makes it only work in landscape (look for overlay size -> frame code)
For GM Demo,
+ Large Overlay View is actually fullscreen now but without ModalViewController container
+ Close Button is now full screen transparent button on Webview Overlays
+ Locked app in portrait
Merge branch 'demos/gm' of github.com:parworks/PARWorks-iOS into develop
