Using nlecomposition and nlesource

[pecisk at gmail.com]

I figured out yesterday that composition's pad-added signal is not firing
(or my callback is wrong), and as a result it does not connect to the rest
of the pipeline. Actual error is because the peers of the composition src
pad are null. I did manual binding and it started working.

Will try to figure out why it happens later.

Peter.
