The way visualization pipelines are displayed has been considerably
reworked. A new class, VisualizationPipelineWrapper, is now responsible
for creating all necessary representations (VisualizationPipelineWidget,
PipelineMdiSubwindow) of a visualization pipeline and seamlessly
switching between them in response to the user's actions (window
dragging, key presses, etc). As a result, it's now possible to drag
visualization pipeline widgets out of the MDI area and turn them into
top-level floating windows.

The main window's central widget has been changed to an MDI area. All
visualisation pipeline widgets are now displayed as subwindows in it.
This approach should help us to better utilise the space in the centre
of the main window.

There is now a new widget (LogViewerWidget) dedicated to displaying log
messages. It builds upon the previous ad-hoc design, adding controls for
clearing and filtering log messages. Clearing has been implemented
already, filtering on the other hand doesn't work yet.

Rendering canvases, as well as the data container inspector, are now
displayed as tabbed docks in the top docking area. The two docks that
were previously located in the right docking area have been moved to the
left to make the layout more intuitive.

We don't use the main window's central widget, but Qt requires it to
exist. This causes certain sizing problems, e.g. docks located in the
top and bottom docking areas don't expand to take up all the vertical
space, which results in some empty space in the centre of the window.
This will hopefully be fixed soon.

logViewerDock is a new dock in the main window. Its main widget is
a QTextEdit to which log messages are appended by a QTextEditLog
instance.

The application is now single-window by default. The floating windows it
was composed of previously have all been docked in the main window.

Certain widgets (e.g. DataContainerInspectorWidget) may have to be
redesigned to better fit this new layout. Also, displaying multiple
rendering canvases at once is not supported yet.

Revised InvalidationLevel concept: InvalidationLevels now directly belong to an AbstractProcessor and are considered to be thread-safe. Furthermore the different levels now really act as single flags that are set (invalid) or unset (valid) individually.
