Until now, the "vertex group" limit method in the modifier only worked for "vertex only" bevels. With this change, edges with both ends in a vertex group will be beveled in the non-"vertex only" case. Also changed the test for being in a vertex group from "any nonzero weight" to "weight >= 0.5". This is because cascaded bevels on disjoint vertex groups did not give disjoint bevels, because weight interpolation would give non-zero weights to newly created vertices in earlier bevels. Chose 0.5 because that won't result from interpolation, but still allows some dilution (e.g., cascaded bevels on the same vertex group).
