Allow connecting to bitcoind through a proxy

It seems like the rust-bitcoincore-rpc library does not currently supports setting a proxy, support will have to be added there first.

I have a fork that does this.

I also needed to patch underlying jsonrpc library and modify a compatible socks proxy. The hard part about this was that rust-bitcoin uses an old version of hyper.

I'm still learning Rust so ^^ are probably crappy. I see there's also some discussion in rust-jsonrpc
