Convert to promises or something async

[linagee]

It doesn't work for me. I'm running Ubuntu 14.10, embark 0.7.0, geth 0.9.39
This seems like a really bad way to implement it (but then, I was told it was a hack, so, eh..)

lib/deploy.js

      while ((receipt = web3.eth.getTransactionReceipt(transactionHash)) === null) {
          sleep.sleep(1);
      }

Sometimes I get "CONNECTION ERROR" (and sometimes it just quietly returned back to my shell without doing anything), I think web3 just trying over and over again to do JSON-RPC to geth. I tried to convert this into a way to use the callbacks on the .new() call to a contract that tell you the address, but then everything else broke. (Such as when it goes to write the ABI, it wasn't waiting for the transaction to finish being deployed, it was depending on this loop to repeat.)

I'm not sure what the best way to fix all of this is, unfortunately I'm not a JS expert. :-(

Good luck converting it to promises/async stuff.

I'll just put my request over there.
