Make Add Land dialog no longer add a random mix of regular and snow-covered basic lands (#9353)

The Add Land dialog now only adds regular basic lands and never snow-covered ones, unless you specifically select a set that only contains snow basics (e.g. MH1) Sets that only contain snow basics are not selectable when adding lands to a Limited deck.
