Working hours should be able to go past midnight

[AlexLerman]

Would be great if working hours could be:

var workinghours = {
        0: ['12:00:00', '04:00:00'],
        1: ['12:00:00', '04:00:00'],
        2: ['12:00:00', '04:00:00'],
        3: ['12:00:00', '04:00:00'],
        4: ['12:00:00', '04:00:00'],
        5: ['12:00:00', '04:00:00'],
        6: ['12:00:00', '04:00:00']
    }

meaning noon to 4am the next day.

Alternatively, a way to have multiple ranges to achieve the same result
var workinghours = {
0: [['12:00:00', '24:00:00'], [['00:00:00', '04:00:00']],
}

I think I've come up with a viable solution: https://github.com/AlexLerman/moment-business-time

I can submit a pull request if you'd like.

Overnight hours can be specified as:

    workinghours: {
        0: null,
        1: ['09:30:00', '28:00:00'],
        2: ['09:30:00', '28:00:00'],
        3: ['09:30:00', '28:00:00'],
        4: ['09:30:00', '28:00:00'],
        5: ['09:30:00', '28:00:00'],
        6: null
    }

Where 28:00:00 = 4:00 AM
