MVC branch initial impressions and list of bugs.

[Wolthera]

Weird crash with animation files, where having an animation in one file,
create a new regular file, and you see the frames from the animation file
in the docker, while the regular file is in focus. Then, pressing play on
the docker causes this crash:

Application: Krita (krita), signal: Segmentation fault
