Added daemon event: DAEMON_EVENT_STATUS (periodically send's daemon statistics.)

 * Improved distributor timeout handling (per-thread).
 * flow-info.py / flow-dash.py: Distinguish between flow risk severities.
 * nDPId: Skip tag switch datalink packet dissection / processing.
 * nDPId: Fixed incorrect value for current active flows.
 * Improved JSON schema's.
