Update for Sneasel ban

As per http://www.smogon.com/forums/threads/sneasel-has-been-banned.3493202/page-5#post-5011892, Sneasel is now banned in LC (LC (beta) being the official Little Cup metagame for XY).

Update for Sneasel ban
Dark Void isn't banned in XY Official Metas
Dark Void isn't available in current XY Battle Spot

Smeargle only learns it through Darkrai who isn't available at the moment, but the legality checker does not catch that.
