Switch to pure CSS3 transforms

The jQuery transit plugin was causing too many issues. Instead, use CSS3
transforms for transforming and flipping cards. Turns out this is much
easier to deal with.

DFCs have both faces constructed at the same time. Clicking the transform
control adds a class that triggers a CSS transformation to animate the
card flipping to the other face.
Fix info panel layout

The tabs need to fill their container completely to ensure the panels'
margin is correct.
Allow switching between versions in the same set

For example, the multiple versions of Fallen Empires cards.

DFCs and flip cards won't switch printings. This isn't a problem for now
since a DFC or flip card has yet to be reprinted.
Mark current printing
Force database upgrade

Clear out both databases to ensure everybody has the most recent versions.
Really the prices DB version needed to be bumped last update. Oh well.
Select set with same multiverseid

Querying by multiverseid should return that exact card.
Increase info toggle size / fix split cards border

Double the size of the info toggle. Can't go much more than this because
we're already bumping up against the transform control.

Adding -webkit-backface-visibility to split cards seems to fix the line
appearing in the border. Strange.
