* Helpers galore This commit adds helper functions that should be commonly needed by many magefiles. It includes command execution handlers as well as error handlers. This commit also removes the only two non-stdlib dependencies in the codebase. Since mage will likely be vendored into a repo, it would be nice to avoid cluttering the vendor directory with dependencies that are only for the build script.
