Type of a token is by default stored as text into attribute 'model'. This is not a reliable method since user can define and overwrite the text.

Token type can be derived from object class (or from user perspective, from a presence of certain fields)

Token type virtual output param should be added to otptoken-find, show and mod commands and into Web UI.
