Add an MP4 video in the stkVideo component in /demo-project/multimedia/video-player. Currently the player only serves a MOV file. One of the key advantages of HTML5 video is the ability to define multiple sources. We should add at least one other format so that users can see this feature in action. MP4 video is common and we explicitly recommend it in the dialog.

Find a .mp4 file of the same video attached. Please add it to /demo-project/videos in the DMS and reference from the video player component.
