- #163 possible fixes for playlist replacement memory leak. unbind and clear all timer events and listeners where completed, use weak references when unable to set listener method callbacks, initialise and reset playlist clips list, reset screen display list when changing playlists. stop and close the connection and stream when replacing clips.

- #104 when completing a seek click or drag, do a final non silent seek request when both paused and resuming playback from a paused seek. This fix also enables seeking while clicking the scrubber when paused.
- #104 if the updated time is a fraction less than the seek target time ie for HDS, use a bitwise rounding so the seek time can stop.

 - #50 if we have metadata already set it is being updated during seeks and switching, dispatch metadata change events instead. new clip event method added onMetadataChange

- #42 when returning and resuming from an instream clip, restart the time update timer.

- #629 if start has been dispatched already prevent dispatching many begin events.
- Fixes for #15

- #614 when the clip ends if the next clip in the provider has a different provider close the provider stream.
- #627 only detach / attach the display on start events which causes issues in buffering events after a seek in stagevideo.
- #627 re-enable stagevideo state change listeners if stagevideo is available or detach the fullscreen events on first call.
