Merge branch 'development' into feature/testnet-faucets/order-dispenser

* development: (49 commits)
  Prettier
  Updated contract generation in 0x to new abi-gen CLI
  Add PR number to changelog
  Fix lint errors
  Removed deprecated CLI options
  Add protected keyword to underscore lint rule
  Remove unused prop
  Fix prettier
  Uppercase Networks enum values
  Make default gasPrice more readable
  Fix prettier mess
  Fix linter errors
  Shrink img
  Fix all setState calls after unmounted errors. Decided to create our own flag rather then using a cancellablePromise since there was little to be gained from this alternative
  Fix bug where we were return undefined instead of the empty object
  Default the derivation path to that found in the Ledger subprovider
  Add browser data to dialog info
  Add Rinkeby support
  Pass in whether we want the personal message prefix appended and never append it for Ledger. This fixes signing when Ledger is used and the backing node is not Parity
  Wholesale replace the tokenByAddress and de-dup properly
