Log invalid chart dirs to stderr (#290)

If directories are deleted from a chart, ct detects them as invalid chart directories. A log message is printed to stdout which messes up the regular output. In order to fix this, the message is now logged to stderr. *Example:* ``` $ ct list-changed Directory 'charts/mychart/templates/deleted' is not a valid chart directory. Skipping... charts/mychart ``` Signed-off-by: Reinhard Nägele <[email protected]>
