[dependabot]

Bumps cosmossdk.io/core from 0.3.2 to 0.5.1.

Changelog

Sourced from cosmossdk.io/core's changelog.

0.5.1 (May 30, 2017)

BUG FIXES:

• fix ibc demo app to use proper tendermint flags, 0.10.0-rc2 compatibility
• Make sure all cli uses new json.Marshal not wire.JSONBytes

0.5.0 (May 27, 2017)

BREAKING CHANGES:

• only those related to the tendermint 0.9 -> 0.10 upgrade

IMPROVEMENTS:

• basecoin cli
  • integrates tendermint 0.10.0 and unifies cli (init, unsafe_reset_all, ...)
  • integrate viper, all command line flags can also be defined in environmental variables or config.toml
• genesis file
  • you can define accounts with either address or pub_key
  • sorts coins for you, so no silent errors if not in alphabetical order
• light-client integration
  • no longer must you trust the node you connect to, prove everything!
  • new basecli command
  • integrated key management, stored encrypted locally
  • tracks validator set changes and proves everything from one initial validator seed
  • basecli proof state gets complete proofs for any abci state
  • basecli proof tx gets complete proof where a tx was stored in the chain
  • basecli proxy exposes tendermint rpc, but only passes through results after doing complete verification

BUG FIXES:

• no more silently ignored error with invalid coin names (eg. "17.22foo coin" used to parse as "17 foo", not warning/error)

0.4.1 (April 26, 2017)

BUG FIXES:

• Fix bug in basecoin unsafe_reset_X where the priv_validator.json was not being reset

0.4.0 (April 21, 2017)

BREAKING CHANGES:

• CLI now uses Cobra, which forced changes to some of the flag names and orderings

IMPROVEMENTS:

• basecoin init doesn't generate error if already initialized
• Much more testing

0.3.1 (March 23, 2017)
