Rewrote some blocks to use sync.Map instead of mutex.
Added PID and process name retrieving for "ps" command.
Added nice output for "ps" command and it is now handled separately, like sysinfo and keylogger.
Devel mode: if message is bigger than 512 chars, console will print only 512 chars.
Laying the foundation for new task-result logic in future:
Task handler: now generates task id for every task.
Task handler: does not delete task after sending to agent, but just marks it as dispatched.
Task handler: operator conn and ID retrieval by task id.
