Revert "* fixes Issue #99"
This reverts commit 97fb9f3c.

If a DataNamePropertyWidget is created for a DataNameProperty whose
AccessInfo == READ, it doesn't instantiate a QLineEdit to display the
property's value (QComboBox is used instead).

Previously, the updateWidgetFromProperty method didn't check AccessInfo
to see what display widget was in use, and simply always dereferenced
the _lineEdit pointer. If AccessInfo == READ, it was null and the
application crashed.

Now updateWidgetFromProperty accesses only the combo box if
AccessInfo == READ, and uses the line edit otherwise.

Fixes #99

* fixed (de)initialization of DataContainerInspectorWidget and its canvas

* work on Columbia module: simple mesh visualization

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.

The QtCanvas class didn't previously implement the sizeHint method. As
a result, Qt would allot it no display space if there were other widgets
competing for it (e.g. the main window's central widget).

Now QtCanvas has a sizeHint implementation that returns a size hint that
is in line with what the canvas' getSize method reports. Moreover,
QtCanvas now uses the `Expanding` size policy to inform Qt that it would
like to get as much display space as possible.

A new class, LogHighlighter, has been added to the application.
Currently it's only responsible for highlighting those parts of log
messages that match the current filter. However, it can be easily
extended to also highlight timestamps, log levels, etc. All in all, this
should make the information the log viewer displays much easier to scan
through.

Typing text into the log viewer's QLineEdit now causes all log
messages that don't contain that text to be filtered out. To
support this, message caching had to be moved to the log viewer.
