Video element in interface

[BrechtDeMan]

Next stage from #138.

Again different scenarios (modes) could be possible possible:

• Associated with stimuli: completely different video shows depending on which fragment is playing.
• Independent from stimuli: in sync but only audio changes (if this is meaningful, otherwise the above option will do). E.g. you see a mouth saying a word and you have to select the corresponding audio. "Does it say 'beer', 'bear', or 'bar'?"
• No audio, just video (for perceptual evaluation of visual stimuli). I suppose this is just implied by having a silent video, unless the audio must always be provided separately.

There should probably be a fixed place for it within every interface style, though size may be an optional attribute. Perhaps other options needed (frame rate, ...).

Hi @BrechtDeMan ! I wanted to add my vote for this feature request. "In sync video, but only audio changes" would be my biggest request. Are there any plan for this in the future? Thanks!
