Modernized Tree View Display

Several changes have been made in 2017-3 to update the look of the Model Information panel in the IFC Viewer.

The Model Information panel, which displays the tree views for a model, now appears on the left side of the IFC Viewer instead of the right. This location mirrors the location of the navigation tree in the main Viewpoint For Projects™ window and in many other commonly-used applications. In addition, the Model Information panel has been updated with a more modern and streamlined look. Thinner borders have replaced the previously bulky ones around the tree views, and the tabs now have definitive, rounded edges, making them more tab-like in appearance.
