Mtg: Format fall rotation and other format validity fixes

Hello guys,

Effective tomorrow Standard & Extended are rotating, so we're updating our legality information to reflect that.

Standard

Standard now has sets Innistrad to Return to Ravnica.

Extended

Extended has Zendikar to Return to Ravnica. Jace, the Mind Sculptor, Mental Misstep, Ponder, Preordain and Stoneforge Mystic are still banned.

Modern

For Modern, we had an oversight in the legality info: Punishing Fire and Wild Nacatl were banned since January this year. We've now updated the info as well. (for reference: http://www.wizards.com/magic/magazine/a … ature/174a)

Also, as of the 1st of October, Valakut, the Molten Pinnacle is unbanned in modern (http://www.wizards.com/magic/magazine/a … /09202012a).

Vintage

Vintage sees Burning Wish becoming unrestricted as of 1st of October as well. Fact or Fiction, Frantic Search, Gush,  were listed by us as restricted but they are not anymore, so we've updated them. Thirst for Knowledge is now listed as restricted.

Legacy

Land Tax[1], Time Spiral are no longer listed as banned. Survival of the Fittest is now listed as banned.
