Assuming the power supply follows the Power Rules, it's a lot more informative to show its PDP than the number of PDOs it advertises. This is the first step towards implementing the new design for showing the Source_Capabilities.
The GUI still works fine with version 0.1, but should be used with 0.2 now that the PID is assigned.
The program structure is no better yet, but it uses the slick new library I made.
