This special purpose UI provides commands that can benefit from direct access to the io.Reader and io.Writers of the base cli.Ui. It can traverse a chain of ColoredUis to find the base. Currently, it can retrieve writers from a cli.BasicUi (or cli.MockUi for testing). Renames ui.go and ui_test.go to log_ui.go and log_ui_test.go
