Delete hotkey added

[fkurmannucsc]

Added a delete hotkey to remove the uppermost item in the screenshot area.

I don't really think this hotkey should exist.
Since we don't currently have a concept of the "selected" screenshot, I don't think we should have a universal hotkey for it.

I agree that having a notion of which screenshot is selected would make sense. Perhaps the selected screenshots should be highlighted somehow and then with the up/down arrows users can navigate which screenshot is selected. May be a larger item but I could start to implement this.

I think you may have missed my point.

This PR doesn't make sense without the selection functionality.
And I am not convinced that we need the selection functionality.
So I think this PR should be dropped.
