Remove async dependency in favor of promises

[marshall007]

It appears that async is relied upon for just two calls to async.series(). Here's my attempt at replicating this behavior using a promise chain. There's still one failing test case that I can't get to pass so I'm hoping someone more familiar with the internals can take a look:

After looking into this further, I think this test case fails because the existing behavior is bugged. Calling .all() or .where() with no parameters is going to default to { lazy: false }. As a result, isn't the expected behavior in this test to eagerly fetch the hasOne relationships (i.e. the GridController associated with each system) as well?

I'd love to drop the dependency to async and meld isn't used anywhere either.
