* Added “export deck” option to export deck to decklist.org for viewing/printing. Implemented using a new menu item, added shortcut ability, and functionality to parse the deck correctly and add main/sideboard cards to decklist. Per issue #2931
This is @mcallahan's patch — see #35. I had to apply this diff by hand,
because both `git` and `patch` refused to apply it and I didn't know
how to resolve that. Consequently, there might be an error.
