Downloader executable does not stop cleanly

[AndreaLanfranchi]

Noticed downloader executable when CTRL+C is hit ends abruptly. Should expect to reach

cout << "Downloader stage-loop ended\n";

But it does not happen: actually is missing

SignalHandler::init();  // Trap OS signals

at the top of code.

Tried to add that and, after rebuild, relaunched downloader and hit CTRL+C ...

but downloader keeps chugging as nothing happened ... Question ... is downloader only a mock or are we missing stopping checks ?

Downloader command is only for test/dev purpose. Anyway I will fix it.
