Collectible Card Game Headquarters

We now have 40 warnings and I think that I can get rid of a few of them. A number of these warnings are coming from classes outside of the forge package:

arcane.ui
arcane.ui.util
org.jdesktop.swingx

I will add the missing serialVersionUIDs and will remove the no longer needed imports from the forge package. Does anyone have any ideas on how we should/could handle the warnings associated with the above three packages?

serialVersionUIDs doesn't matter unless you serialize the class, so these don't really matter here you could use serialVersionUID = 1L if you really don't want those warnings or switch them off in your project options
