Missing requestExitFullScreen message in CreativeMessage dictionary

[jakraskin]

Hi IAB,

We noticed that the CreativeMessage dictionary does not currently contain a constant for requestExitFullScreen. Can we please update the sample code to include something like REQUEST_EXIT_FULLSCREEN in CreativeMessages? Having the constant explicitly defined would prevent creatives and players from potentially using different constants for requestExitFullScreen (e.g., REQUEST_EXIT_FULLSCREEN or REQUEST_EXIT_FULL_SCREEN).

Thanks! Josh
