v2.5.0

This MINOR release of purser introduces basic support for chain definitions through the ethereumjs-common package.

purser-core now has an internal helper for dealing with this: getChainDefinition, which in turn, is being used through the Ledger, Trezor and MetaMask packages.

This basically adds in support for custom chains. It's still pretty basic, as some chain IDs might fail ethereumjs-commons internal validation, thus the transaction failing to sign.

Thanks again to @JamesLefrere for having to deal with all the ethereumjs-tx changes and updates.
