* NEW: Invert the argument order (again) in MediaControl constructor. The
parent comes first, the control type next.
* NEW: Now the MediaControl link methods are LinkTo() and LinkLaterTo().
LinkTo() has two optional arguments that allows to link specific inputs
and outputs by name. LinkLaterTo() link to another control just after a
new pad has been internally added.
* NEW: MediaContainer got two new methods, AddInput() and AddOutput(), to
create ghost pads, i.e. symbolic links on child inputs or outputs. By
default a MediaContainer has no input and no output.
* NEW: Media.URL() is a new method that returns a GStreamer URL from a file
path. If the file path is relative (i.e. a file inside the project), a
temporary copy of the project file is made and returned.
* NEW: MediaPlayer got new properties to redefine its input, video output,
audio output and subtitle output.
* NEW: MediaPlayer.Video.Visualisation is a new property that defines an
optional visualisation plugin used when there is no video to play.
* BUG: The MediaPlayer SourceSetup event has been removed, because the
underlying signal must be handled immediately in thread context,
otherwise it is useless.
