API Breaking

• (core) #227 Remove sdk.Result from application callbacks.
• (transfer) #350 Change FungibleTokenPacketData to use a string for the Amount field. This enables token transfers with amounts previously restricted by uint64. Up to the maximum uint256 value is supported.

Features

• #384 Added NegotiateAppVersion method to IBCModule interface supported by a gRPC query service in 05-port. This provides routing of requests to the desired application module callback, which in turn performs application version negotiation.
