Spam: The other white meat

Here's the cleaned up version of the media mover hook. Changes are: renamed "new_config" to "new config", added "edit config", created support for editing and deleting individual configurations. There's quite a bit of clean up on the main media_mover module in this round, but obviously there is a fair bit to go, particularly in the admin side of things.

I'm considering adding a testing option into the hook to provide the admin an opportunity to run a config and see live error reporting on a specific configuration. Since there are potentially so many places for issues, it would be nice to get a report instead of digging through drupal's error logs.

Additionally, while the module currently runs on cron, I'd like to expose each configuration (ie: a set of harvest, process, and store settings) as an action so that a specific configuration can be run via workflows. Originally, I had planned on integrating this system directly with workflows, but I think this is a better way to integrate because of the tight integration between the three parts of the process.
