Transaction signing and encoding (#95)
* WIP setting up evm tx command and updating emint keys output

* Fix linting issue

* Wip restructuring to allow for ethereum signing and encoding

* WIP setting up keybase and context to use Ethermint keys

* Fixed encoding and decoding of emint keys

* Adds command for generating explicit ethereum tx

* Fixed evm route for handling tx

* Fixed tx and msg encoding which allows transactions to be sent

* Added relevant documentation for changes and cleaned up code

* Added documentation and indicators why code was overriden
