Add tagging to create an option when it doesn't exist

[JLEGit]

Notes from library author:

• Could be named "tagging" as this is what vue-multiselect and vue-select have already implemented.
• Add a :taggable prop that can receive a boolean.
• When :taggable="true", if user search for an option that isn't part of the list, ask if they want to create it instead in the menu.
• There's potentially a lot of edge-cases to handle with this feature (adding/removing a created option, how to create the option value, etc.)

Would be nice to have a bit more details on the issue, but I agree with your point.

I'll edit your comment with the specs.

Would really like to have this function as well.

Is this in progress, or does this have no priority at all?

[TotomInc]

@robinvoor there aren't any priorities actually and there isn't any work in progress for this feature. Feel free to create a pull-request if you're willing to work on it :)

However, this feature can be quite challenging. We need to define how to handle the v-model when a new value is tagged/created.
