Given that we have to run a few dozen onionbalance instances, it'd be nice if there was a way to tell them apart.

Currently, ps output looks like this:

onionba+  6034  0.4  2.3 335672 191900 ?       Ssl  Apr20 183:46 onionbalance
onionba+  6035  0.4  2.2 334900 185064 ?       Ssl  Apr20 180:44 onionbalance
onionba+  6036  0.4  2.2 335356 187052 ?       Ssl  Apr20 184:50 onionbalance
onionba+  6037  0.4  2.2 335668 184096 ?       Ssl  Apr20 183:52 onionbalance
onionba+  6038  0.4  2.1 336176 173472 ?       Ssl  Apr20 182:55 onionbalance

Thus, please remove the setproctitle('onionbalance') in manager.py or do some other smart thing.
