Fixes #67.
getClientIponly checked truthiness of the rawX-Forwarded-Forheader before using it, not whether it was meaningful after trimming. A whitespace-only header (e.g." ") passed the presence check, got trimmed to"", and that empty string was returned instead of falling back toreq.socket.remoteAddress.Now the trimmed forwarded value is only used if it's non-empty; otherwise it falls back to the socket address, same as when the header is absent entirely.
