I'm inclined not to support it, because it seems to duplicate the job of multitask configuration for little added benefit. The benefit as I see it is only that the build/tests run once and then multiple deploys get fired off, but we could support that as well by allowing multiple params after lineman deploy (e.g. `lineman deploy production1 production2`)

I do think the maintenance and confusion cost of supporting this array style in addition to multitask option propagation wouldn't be worth it. My sense is that your example config actually solves more-or-less the same problem multiTasks would
