Transitioning to using ListView to show images.
The old widgets are not yet removed. A LOT of old sh*t needs rewriting for removing them. (Note to self) Other TODOs: - Convert all keyevents to qactions. - Convert main window to an actual main window. - Move file loading logic out of main.cpp (or not, doesn't even matter). - Move subsliced signatures into library.
