[packman] mlt/melt/kdenlive

[Christoph Walzer]

This is what i got form the mlt guys:

> This is fixed in MLT git, but there is another somewhat new problem
> when the MP3 has album art. FFmpeg is exposing that as a video stream
> with a crazy framerate that is confusing MLT.

Not too many people want to cope with source based deviations (and breaking) 
of their distributore's package structure i guess (i don't, i'm lazy). So
should the mlt packman packages respect the new dependency? Does packman's
policy allow to update to mlt's git version?
