Implement tree view for experiments

[swagner]

It would be nice to have an alternative view for experiments which shows an experiment and all its contained sub-experiments, batch runs, algorithms, etc. in a tree view.

r6423: Refactored optimizer views to derive from common base class IOptimizerView.

[mkommend]

r6471: Implemented experiment tree view.

[mkommend]

r6485: Added remove by keystroke functionality and refactored the code.

[mkommend]

r6488: Fixed docking issues with expanded nodes.

[mkommend]

r6496: Added functionality to open new view on double click.

[mkommend]

r6498: Corrected tree node stated (expanded / collapsed) after double click.

Treenodes toggle the collapsed / expanded state on mouse click.

r6513: Corrected toggle of collapse / expanded state of treenodes.

Review comments concerning functionality and UI:

• A context menu to recursively collapse all contained nodes of a node would be nice.
• Experiments, batch runs and algorithms are very hard to differentiate. They should have different icons (e.g. differently colored flashes) or a prefix in the label text or ...
• It would be very comfortable, if algorithms could be expanded so that the contained problem and the parameters are shown in the tree view.
• It would be nice to be able to change the name of an experiment, batch run or algorithm by editing the tree node label in the tree view.
• It would be nice to support drop actions also for batch runs (i.e. set the optimizer of a batch run by dropping one on it).
• The responsiveness of drag operations seems to be a bit slow. Maybe it can be optimized a bit to react more quickly?

• Added algorithm child nodes (problem, parameters, results)

r6531: Corrected enabled state of add button.

[mkommend]

r6534: Changed icons for batch runs and experiments.

[mkommend]

r6539: Optimized rebuilding of the image list due to performance reasons.

[mkommend]

r6542: Corrected SelectedItemImage and registering of algorithm events if the problem gets changed.

Review comments:

• The result collection shown in the details group box when clicking on a results node in the tree view is not updated when an algorithm is prepared and started again.
• Additionally to the context menu it would be nice to allow editing of tree node labels also by pressing F2.

The first comment is quite critical. If possible, please try to fix it before the 3.3.5 release.
