Can't find contracts imported from node_modules

[davesag]

I'm using Truffle 4.0.1

Some of my contracts import 'zeppelin-solidity/contracts/token/ERC20.sol'

• Running my tests from within truffle develop is just fine.
• Running my tests by running up my own testrpc and running truffle test runs just fine.

Running solidity-coverage however fails.

Error: Could not find zeppelin-solidity/contracts/token/ERC20.sol from any sources; imported from /Users/davesag/src/myawesomeproject/coverageEnv/contracts/Escrow.sol

You need to set the copyNodeModules flag to true in your config. This will increase runtime; if we can get #117 working everywhere, then you would be able to specify just the zeppelin contracts, but that's not possible for now.

Cool that worked kind-of. I've raised a separate issue, #153 for the error I am now getting.
