Improved performance

Before value was translated to a C type variable two times,
at the reception then at the emission. Now it just receives
and sends the signal value without translation nor interpretation
except if you ask for an average, minimum or maximum value. Then in
those cases it interprets the json to return you a value or an
error if there is no numeric values to compute.

Remove unneeded log message at event reception.

Improved signal search engine, will search in source's signals map
by the signal ID not the event name which lead to a more direct map
match.
