* renamed VideoInfoItem to VideoPreviewInfo * moved streaming service-related classes into their own, new package services * added javadoc to some classes and methods (where functionality is known well enough to explain) * De-duplicated common fields between VideoInfo and VideoPreviewInfo by moving them into a common superclass: AbstractVideoInfo * Removed 2 methods which only call super(), and therefore are unnecessary: PlayVideoActivity.onResume() and PlayVideoActivity.onPostCreate(Bundle)
