users may wish to upgrade some dependencies ahead of cabbage's own releases (e.g. a broccoli plugin adds a new option and cabbage isn't updated to include it)
basically, every place we require testem or a "broccoli-*" plugin we should first resolve off of process.cwd() (as we do when we load broccoli itself) and if resolution fails, fall back on built-in require resolution.
