Align comments on object items

[clofresh]

Would be nice to have this:

var options = {
    dothings: true,    // extremely important
    numberofthings: 10000, // yeah!
    dontscrewup: true,   // also important
}

Map to this:

var options = {
    dothings: true,        // extremely important
    numberofthings: 10000, // yeah!
    dontscrewup: true,     // also important
}

Or even this:

var options = {
    dothings:       true,  // extremely important
    numberofthings: 10000, // yeah!
    dontscrewup:    true,  // also important
}

this should be implemented by an external plugin. see #233
