[rpc blockchain] Add support for mediantime, chainwork to RPC getblock.

[moodyjon]

Fixes #52

There is a "fee" attribute of nested transactions that I could not implement because I can't find the TxUndo information. Don't think that feature exists in lbcd or btcd. In C++ bitcoin, it's stored on disk I think.

"fee" : n (numeric) The transaction fee in BTC, omitted if block undo data is not available
