Change background animation in IntroActivity from Video to GIF.

The video background animation was giving errors on Android Lollipop and wasn't displaying correctly. Searching on the internet I found that the encoding of the video could be the problem but tested with many different encoding profiles (H.264 high, main, baseline) and none of them solved the issue so I finally gave up and converted the video back to a GIF and used that one.
