Crashes during data collection

Current behavior:

Traceback (most recent call last):
  File "./socmap.py", line 103, in <module>

TypeError: {'USERNAME OF ACCOUNT WITH NO RETWEETS'} is not JSON serializable

Looks like there's an errant line in acquire.py that reads:

saveUserList(options.workdir, "layer" + str(layer) + "startingUsers", set(userlist))

My guess is we tried to save off a list of the users we were working with, but saveUserList expects a dictionary of src->destination. Whoops.

Fixed now, just had to pull that line of code out.
