SECURITY: API: Don't log "sensitive" parameters

Stuff like passwords and CSRF tokens shouldn't be in the logs.

The fact of being sensitive is intentionally separated from the need to
be in the POST body because, for example, the wltoken parameter to
ApiQueryWatchlist needs to be in the query string to serve its purpose
but still shouldn't be logged.
