Implement eth_getLogs

[austinabell]

• Will need to implement log reconstruction
  • See Ethereum Yellow Paper 4.3.1 for nitty gritty
  • Might be able to use Geth
• Note: logs are not stored, they typically have to be reconstructed from the txs and validated

@dutterbutter Did #120 close this or is there more work to be done?

[dutterbutter]

More work still needs to be done. Such as having the block hash entered during log entry.

Hi, thanks for the great work on ethermint. We are very interested in testing some applications on it.

For this reason I was wondering if you have any details on when you expect the functionality around eth_getLogs, eth_newFilter etc. to land?
