Fix skipping to next episode

[nielsvanvelzen]

When a media segment skips to the end of the video, the app would misbehave and often just close the player instead of going to the next item. This change adds a fast-path to prevent this from happening.

Changes

• Prevent CustomPlaybackOverlayFragment from navigating multiple times
• Add "skipToNext" option to PlaybackController.seek to allow skipping to a next queue item if the position is at the end of the current item (>= duration - 100ms)
