Duplicate offer item

[johnnywo]

Hi, it would be really nice if I just could clone an existing offer item (and apply small modifications afterwards). Instead of running the process of creating a new one each time.

Thank you,
Emil

@johnnywo, such a good idea. We'll develop it some. Feel free to develop it by yourself and send a PR.

@lautsevich thank you - if I feel able to do that I will!
