All Commander Precons in Cockatrice format

Importing decklists into cockatrice takes much more effort than it should right now due to all data formatting silliness like Unicode apostrophes, various ways to spell "Aetherling", utter insanity of how split cards are being named and so on. Even on Wizards' own website's decklists tend to have a lot of issues.

To make this more automatic I wrote txt2cod script that handles most of such issues. It's available on github (requires Ruby 2.0 and trollop gem) together with my other Magic-related scripts.

And while I was at it, I converted all 10 Commander precons into cockatrice format. That's a good starting point if you want to play casual Commander online. Of course if you're more into Vintage Singleton feel free to completely ignore all of it.
