1.89 released

During the last release, a change in the way magiccards.info served images revealed a bug in the way we deal with corrupted image downloads. We have since patched the 1.88 release to fix this issue.

In line with the recent rules update, the Planeswalker Uniqueness rule is removed and the Legendary supertype added to existing planeswalkers.

In addition, this release includes 10 bug fixes and 175 new cards.
