Now suppress loading messages
Now suppress loading messages

Chicken won't become available to Geiser until it's actually done
loading. A number of bugs are related to this, including jaor/geiser#68
but also some quizzically flaky completion behaviour.

The fix is to suppress output to STDOUT until Chicken is ready; output
to STDERR is not suppressed, so if bad things happen it will still
appear in the geiser messages buffer.

This may fix jaor/geiser#68
