V1 contract(s) verification on Etherscan for Ropsten

[Pongch]

Issue Type

[ ] bug report
[x] feature request

Current Behavior

currently contract is not verified on Etherscan, so all transactions inputs/ logs are not human readable

Expected Behavior

inputs, function names and log of events should be human readable as opposed to hexadecimal

Steps to Reproduce

go to the following link for Plasma framework contract: https://ropsten.etherscan.io/address/0x96d5d8bc539694e5fa1ec0dab0e6327ca9e680f9#events

Suggested Fix

verification via Etherscan

Potentially by API and put it on CI or migration script: https://etherscan.io/apis#contracts

(oh...import limit + library amount limit 😅)
