Added additional (minimalistic) detection information to flow updates.

This will only affect flows with the state `FT_FINISHED' (detection done).

 * nDPIsrvd.py: force use of JSON schema Draft 7 validator
 * flow-dash.py: gather/use total processed layer4 payload size
 * flow-info.py: added additional event filter
 * flow-info.py: prettified flow events printing whose detection is in progress
 * py-semantic-validation.py: added validation checks for FT_FINISHED
 * updated flow event JSON schema
