encydink: built-in haptic video encoder

[qdot]

Build basic video encoding capabilities into Syncydink. This should basically replicate the Blender UI for the moment, meaning:

• Zoomable timeline with all actions
• Points on timeline should be selectable/movable/deletable
• Keyboard overrides
  • move forward/backward in movie
  • 0-9 for position entry
• Output to funscript (other formats can come later)
• Timeline playhead position should follow movie if movie is play. Similarly, if playhead is scrubbed, movie should react accordingly
