Hmm, I'll suggest that for now, if anyone have interest in quickly shipping this
patch for 0.16, we just see the overall (last button on quest window) and print
somewhere (possibly there) something like: 'Blood Killer - Killed 1,000 robots'
when number_of_killed_robots exceeds 1000... And use a if-elif-else style so we
replace it with differents awards.

Now, that is only efficient if someone wants to show that on future we may have
something like that. Otherwise, it's better wait for 0.16 release and do
everything correct since start.
