Added Swing TableModel for data grid display
Redesigned ConfigurationDialog

ConfigurationDialog now has list of configurations aligned to left,
main part of the windows is now the table displaying data (no data yet,
though).
Changed WindowListener to WindowAdapter

ConfigurationDialog currently processes just one type of event, using
WindowAdapter instead of WindowListener reduces clutter.
Fix: MainWindow now has dimension set in ctor

MainWindow initially is maximised. Its dimension was not set, which
caused its drastic collapse to a really tiny narrow sliver (at least
when run on Unity desktop) when the window is de-maximized. Now the size
is set in the constructor, and MainWindow assumes it upon
de-maximization.
Prepared ConfigurationsDialog for data display

Structure of ConfigurationsDialog has been changed to make it fit for
its new purpose - to display data in tabular form. Several visual
upgrades have been made as well.
Added filling ConfigurationsDialog table with data

Model for table is created and used, but there is no way to parser
arbitrary data file for now. Such functionality is out of scope of
GUI/visualization task, and it would probably be useful in more
situations. Once this is in place, this piece of visualization task can
be completed.
