Subject: 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.
