Short description: Add the option to select alternate mask textures/colors when buying masks through the mask store.   Detailed description: Every mask has multiple textures, colors, and variants but we've never had the option through the mask store - I feel like now's the best time to change this.   With the recent rework, fix and implementation of new facial hair "masks" there's actually alternate hair colors hidden in the files but you'll never be able to actually use them
