Issue 258 -- FixFullScreenVideo -- Initial Commit

The use of onShow in the FullScreenVideoUtil
has been replaced with the  use of onStart. The exact code
called in the onShow method is now called in
onStart so that older versions of Android will not generate
errors when trying to access the classes associated with
onShow.
