Investigate reporting multiple wiring errors

[briancavalier]

See discussion here. Rather than failing fast on the first rejection, it's possible we could use when.settle to allow all wiring promises to settle and then report the subset (if any) that rejected.

We should at least investigate whether this is possible and useful.

Just coding out loud....

var err;
settled.then(function (descriptors) {
    descriptors.reduce(function (errors, d) {
        if(d.state === 'rejected') {
            errors.push(d.reason);
        } 
        return errors
    }, []);
    if (errors.length > 1) {
        err = new Error('Multiple errors encountered during wiring. See errors property for details.');
        err.errors = errors;
    }
    else {
        err = errors[0];
    }
    require.error(err);
});

Yep, that pretty much looks like how we'd do it.
