Fix solc usage about poa-network-consensus-contracts HOT 4 CLOSED

poa-bytecode script require('solc'), but solc dependency is missing in the package.json.

Yes, I added solc into scripts/package.json in #139 - it's waiting for approval.

It needs to be clarified if solc binary should be installed separately and how to use it

@rstormsf @vbaranov please, take a look at step 2 on this page - is it still required to use solc not from npm for some reason? What's the reason to use binary package for solc instead of npm's?

from poa-network-consensus-contracts.

@varasev we were using a binary package of solc because it was a requirement of using Python Solidity flattener. I think we shouldn't depend on it anymore. Instead, we could use truffle-flattener or POA Solidity flattener 😄, the first one is more preferable because it has an npm package. I guess we could change flattener in frames of #139 PR and also change README sections:

1. Prerequisites section
2. Start POA Network section

After that we could change a wiki guide

@vbaranov I tried to install truffle-flattener, but the last version of its package (v1.2.5) contains a critical vulnerability. I propose not to change flattener until we see a new safe version.

Done in #139.
