Minor Improvements to the User Interface

There are several minor improvements to the user interface. We have a goal that each new version of our software should not only be more powerful but also even easier to use, and the improved ease of use often appears as information that is better organized or being able to access information more easily. For example, when customizing a wheel, it was not completely obvious that clicking on the planets or "Asteroids/Lots" check boxes in the "Planets" tab opened a window that allows you to select which planets, asteroids, and lots are desired in the chart wheel. This has been made more obvious by placing this text in a button rather than simply being a caption for the check box.
