* Deck editor drag and drop was broken by the window borders change. Still not entirley sure what the root cause is (for some reason SwingUtilities.getDeepestComponentAt won't work correctly with the new setup), but this will fix it by expliticly specifying a deeper root component to start the search from (The MagePane that is active to be specific).
I used Intellij IDEA to automatically refactor code to achive 3 goals.
1) get rid of anonymouse classes, and replace the with lamba to get more readeable and clean code (like in TableWaitingDialog).
2) make effectively final variables actually final to avoid inadvertent changes on it in further releases and keep objects as immutable, as possible.
3) Get rid of unused imports (most of the changes) in whole project classes.
* Working standalone proof-of-concept application in DragCardGrid.
* Still needs listener functionality in order to integrate it into the existing DeckEditorPanel class.
