Is it a problem because MetaMask already injected an old 0.20 web3 version ? How is this handled best?

This message appears after doing a fresh migration, because the contracts file is both in the builds directory and the src you will need to delete the contracts folder in the src directory and copy it from the build directory each time a new build folder is created...

Warning: Defining constructors as functions with the same name as the contract is deprecated. Use "constructor(...) { ... }" instead.

The above warning is shown when compiling the contracts.

Truffle now supports 0.4.24 of Solidity. We should probably update the pragma statement.

Unfortunately I don't have a Windows machine, but in order for Windows support to work, we need to make sure that the symlink is created automatically when unboxing happens. Currently, that is done by running an NPM script npm run link-contracts, but since this uses ln -s, it only works on Linux and Mac.

We basically need a "cross-env" way of doing this.

Could you please add a license file? Everything else looks great.
