Soul Bound Token Implementation

Overview

Implementation of Soul Bound Token concept, introduced by Vitalik Buterin in the paper https://papers.ssrn.com/sol3/papers.cfm?abstract_id=4105763. As in it's nature, SBTs are non-transferable ERC721s, the propsed implementation extends the widely known ERC721 contract, by overriding all methods related to transfers. Several additional functions are added for issuing and revoking SBTs, using the respective modifiers.
