Title: Set 401 and WWW-Authenticate when authBasic() returns false

See discussion on Issue #49 for background on why I am sending this pull request.

Previously, if authBasic() returned false (possibly due to invalid credentials), a 200 OK was returned, even though the restricted content was not being returned. This pull request modifies this behavior such that a 401 with a WWW-Authenticate header is returned instead.
