Add batched update option for interactive mode

[XOR-op]

This PR add support for batched update option for interactive mode.

To be specific, I add option b for each interaction. And for each app answered with b, I record it in a temporary list, then perform upgrade after all interactions are answered.

Fixes #182 (asks for the same feature enhancement)

Thank you for your contribution @XOR-op 🙂 I was just wondering, why you went this path? My idea was to not have yet another option but change slightly the way it works - you would add it to the batch when "y" was given and then do the upgrades. Do you think it makes sense? Could you make that change?

You're right. However I have no experience in Ruby, so I'm not sure if I would break something in that manner. Also I've pushed a new commit to recover original flag.

Hey @XOR-op , I've come up with an alternative, where I first asks for the input and then execute it. Feel free to look into the solution or propose any changes (#224).
