Converting images from Qt <-> PIL

https://stackoverflow.com/questions/1733096/convert-pyqt-to-pil-image#1756587

note: likely embarassingly slow, so we need to be careful about this

Overriding closeEvent to allow "Are you sure you want to quit dmclient?"

better strategy: just autosave the campaign progress!

Utilise parts of Qt to avoid having to write too much code.

-> use QStyledItemDelegate and QItemEditorFactory

see: http://www.diusrex.com/2014/09/qt-modelview-editing-tutorial/

also see, for a discussion on using dialogs:

https://stackoverflow.com/questions/22868856/qfiledialog-as-editor-for-tableview-how-to-get-result

Use setInformativeText in dialogs. One way might be to have dialog text be two

lines: first line is setText. second line is setInformativeText.

Shortcuts are weird.

"New Campaign" has ^/⌘n

New Encounter from Template has ^/⌘N

New Session isn't in File menu

How often is each action? Yeah...

Ugh, QLineEdits/etc? don't have their own undo/redo model built-in. So we need

to hack those in.

Interesting question: does this fit with global undo/redo?
