[GSoC status report] Week 4

[Téo Mrnjavac]

This has been a reasonably productive week. I've fixed another weird
crash with no backtrace (and learned to be more careful when using
named ctors) and handled some important details in ffmpeg's syntax and
its use through KProcess. I've added some more customizations for
Vorbis encoding parameters, but then I've scrapped most of the testing
UI for that and started working on the real thing. After the issues at
the sprint in Randa, transcoding works again. Currently, this [1] is
what the user would get if the tried to copy a track, though for now
it only works from the file browser. The idea is to allow sane,
context-sensitive and clearly documented defaults for noobs and more
detailed encoder configuration options for nerds, and I believe that
QCommandLinkButtons could be the right thing to use here in order to
keep things simple and pretty.

Next week, more UI and replacing the stubs in TranscodeFormat with
real ctors for formats other than Vorbis that we definitely want to
support.
