Currently the batch-task plugin only supports the batch script action, but it is
sometimes useful to execute tasks that are defined as ant targets or in other
forms. I'd love to see support for the full breadth of action types available
in Hudson.

FYI, you may be able to model this on the code used by the promoted-builds
plugin, which already supports the full range of actions within promotion
processes. I can use that plugin as a workaround now, but sometimes the
implications of a "promotion" don't apply to a task, so the promoted-builds UI
doesn't make sense.
