Welch's ANOVA (unequal variances)

This analysis now lives inside One-Way ANOVA. Welch's ANOVA is now the DEFAULT engine for One-Way ANOVA, so a separate card would run exactly the same analysis. Open One-Way ANOVA and you get Welch's F* with Games-Howell post-hoc; the classical (Fisher) F with Tukey HSD is reported alongside it for reference.
