Add ctrl+Return shortcut to mark item as complete

[mcorteel]

This is really missing. I'm not sure if my PR actually works, but I guess that the change should look something like that.

Is this a standard shortcut for something else? It's not a shortcut in Google Tasks.

[mcorteel]

I don't know if it's standard or if that's the particular shortcut that should be set, but IMO there should really be a shortcut to mark an item as completed (it may also switch the completed status). Google Tasks uses alt+Return.

[Zren]

I'll add a || "alt+Return" conditional after the merge so it's familiar with google task users too. That should hold them off till I figure out a way to make configurable shortcuts.

Also made it toggle instead of just setting complete=true.
