Fix jgoodies-forms 1.6 deprecation warnings
The PanelBuilder setOpaque and setBorder methods have been deprecated in version 1.6 and have been removed in 1.7 (which isn't available in the maven repository yet).
Since 1.6 the PanelBuilder's opaque state is false by default, where it was true before. (http://www.jgoodies.com/download/libraries/forms/RELEASE-NOTES.txt)
- Remove or rename setOpaque -> opaque
- Remove or rename setBorder -> border
