Fix 204 responses, hangs and crashes with REST.
Remove Content-Type and make sure no content is returned by OPTIONS
request in REST interface.
In write_html set the Content-Length when response is not
encoded/compressed (fixes hang due to missing content-length with
unencoded data).
In REST interface do not raise UsageError for invalid api version.
Return json error with proper message. Fixes crash.
