More precise encoding report in the expert window

[kawamoto76]

I want that the expert windows log will report more precisely, otherwise I can not know what happened.

A expert window log is shown below.
This is when a conversion(from TS(mpeg2-aac) to .m2ts(H.264/ac3)) terminated on the way.

The 8th line "Encoder terminated unexpectedly." does not report Encoder's name, then I can not know which was terminated, x264 or ffmpeg.
The 9th line "encoding thread to exit" may report ffmpeg would terminate, but not described explicitly.
The 10th line "Waiting for process to terminate" does not report explicitly what process had been waited to terminate.
