[Feature request] Handling paste and then split it

Hi,

It would be a great addition to have a `Ctrl+V` (paste) event handler for the TagsInput component. Specifically, when a user pastes a comma-separated list of IP addresses, like `82.32.121.39,5.12.49.203`, it would be awesome if the component could automatically split the string by the commas and add each IP address as an individual tag.

Cheers
