Supersedes #98
Adds a new method
JsonRpcEngine.destroy(), based on this hack in the MetaMask extension: https://github.com/MetaMask/metamask-extension/blob/851fce9a3b155265c3eac3efe82474a0181de99e/app/scripts/metamask-controller.js#L2785The
JsonRpcMiddlewaretype is altered to permit adestroyproperty. CallingJsonRpcEngine.destroy()clears the internal middleware array, calls thedestroy()method of every middleware with such an own or inherited property, and renders the engine instance unusable.Kudos to @daoauth for the original implementation.
