* (rpc) [\#231](https://github.com/cosmos/ethermint/issues/231) Implement `NewBlockFilter` in rpc/filters.go which instantiates a polling block filter
* Polls for new blocks via `BlockNumber` rpc call; if block number changes, it requests the new block via `GetBlockByNumber` rpc call and adds it to its internal list of blocks
* For a given filter, look through each block for transactions. If there are transactions in the block, get the logs from it, and filter using the filterLogs method

* (`x/evm`) [\#176](https://github.com/cosmos/ethermint/issues/176) Updated Web3 transaction hash from using RLP hash. Now all transaction hashes exposed are amino hashes:
