(app) #188 Misc cleanup @fedekunze:

#236 Changes from upgrade @fedekunze
- (app/ante) Moved AnteHandler implementation to app/ante
- (keys) Marked ExportEthKeyCommand as UNSAFE
- (x/evm) Moved BeginBlock and EndBlock to x/evm/abci.go

(rpc) #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
- Update uninstallFilter and getFilterChanges accordingly
- uninstallFilter stops the polling goroutine
- getFilterChanges returns the filter's internal list of block hashes and resets it
(rpc) #54 #55 Implement eth_getFilterLogs and eth_getLogs
- 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
- eth_getLogs and eth_getFilterChanges for log filters use the same underlying method as eth_getFilterLogs
- update HandleMsgEthereumTx to store logs using the ethereum hash
