A macro to generate a new integration test case

The forgetest! macro’s first argument is the name of the test, the second argument is a closure to configure and execute the test. The TestProject provides utility functions to setup the project’s workspace. The TestCommand is a wrapper around the actual forge executable that this then executed with the configured command arguments.
