Add Sampler classed and the vidi-player.py and vidi-sampler.py programs

vidi-player.py plays midi files in real-time, instead of waiting for the
timeline creation like vidi-timeline.py does.

vidi-sampler.py plays samples according to the notes produced by a midi
controller.

Rename vidi-player.py to vidi-timeline.py

The name vidi-timeline.py reflect better what the program actually does:
generate GES timelines.

This also frees the spot for a possible future vidi-player program,
based on GStreamer, which plays midi files live without having to
generate the GES pipeline beforehand.
