onMentionSelected hook

This would allow developers to specify how to render their selected mention. It should also be possible to allow them to make the suggestions array data any data structure they want, since they can just format it at the end to fit into the editor.

I think a corresponding function that you might need is onMentionBackspace. The default can be the function that you have right now but the user can override it.

Agree, what about calling them onMentionSelection and onMentionDeletion?

Maybe onMentionInsertion instead of selection (since arrow keys are technically selecting it?)
