[Cin] Forum Video Tutorials

[Andrea paz]

@IgorBeg; Usual request to put on the forum the video of the
manipulation of the tracks in the timeline.
@All; There are now many good video tutorials made by IgorBeg and
Phyllis. Having them on streamable is not ideal for their visibility:
you can only access them through forums or mailing lists. My proposal
is to upload them to CinGG's Youtube channel, which for now only shows
the translation tutorial. Is such a solution possible?
