More Drag & Drop editor fixes

* Fixed cards being blurry. The problem isn't completely fixed, but the fix will suffice in most cases. Card Images are only loaded in once, and the cards were loaded in initially at a small size instead of their eventual size after layout. Really they should reload images when resized, but I will tackle that later, and it's only noticable when significantly resizing cards within one usage of the editor anyways.
* Removed some of the unneeded UI on the sideboard half of the DeckView so that componently are less likely to overlap at a small size. Not sure how to ideally handle this, as Swing doesn't really provide an elegant way to hide components at small sizes, and I'm sure the user would rather the components overlap than be unable to resize the window as small as they want due to a minimum size requirement.
