* fUSDC with 6 decimals (like the real USDC)
* update truffle verification plugin

 * `IUserDefinedMacro`: added a method `postCheck()` which allows to verify state changes after running the macro.
 * `SuperfluidFrameworkDeployer` now also deploys and `MacroForwarder` and enables it as trusted forwarder.
+* `deploy-test-environment.js` now deploys fUSDC (the underlying) with 6 decimals (instead of 18) to better resemble the actual USDC.
