Start of sprites (#17)

* Adds sprite model with experimental drag & drop functionality for the sprite editor (can later be turned into generic drag and drop model for other views)
* Removes unused include to `Background.pb.h` in `MainWindow.cpp`
* Removes custom dynamic "Josh" property from background editor I was experimenting with and mistakenly merged
* Changes the margins of the layouts in various places so the edges are not right up against the subwindow borders
* Made Smooth, Transparent, and Preload have a consistent layout for the sprite and background editors
* Configured more label buddies and mnemonics for several of the layouts
* Tweaked the layout of the sprite editor so the preview area is bigger than the subimage list
