Playback Speed in player needs more useful defaults

Steps to reproduce

Steps to reproduce:
1. In the player we have currently playback speeds from 50% - 150%
2. Feedback from students suggests to skip 50% as it might be too slow and add faster playback speeds
3. Improving the keyboard shortcuts could make the function even more usable.
