UI Overhaul!! :)

I finally got the UI working in a way I like. You now have one panel per component.

The Structure

The window contains a JScrollPane (for scrolling when the content gets larger than the window) which contains a JSplitPane for dividing the contents into top and bottom.
 
Additionally, there are the TopPanel and BottomPanel. The TopPanel contains three fixed panels: CPU, GPU and RAM. (still need to figure out how to properly display multi-GPU setups like this but future problem i guess)
The BottomPanel contains all other devices, like drives and network adapters.

Technical Details

Both TopPanel and BottomPanel are containers for individual “component panels”. Each component panel (CpuPanel, DiskPanel, …) owns its own components like labels, graphs or similar. I also wrote a custom JPanelRounded class for rounded panels.

About to add a little detail to the component panels next! :)
