Use promisify for web3 sync functions #219

Closed s1na closed 6 years ago

s1na commented 6 years ago

Hey guys. I'm sorry for the delay.

I've tried to find every instance of web3 synchronous calls, and make them async via node's built-in (>= v8) promisify. Please let me know if you'd prefer a different approach, or if there are calls I haven't converted.

Fixes #205
