Smooth out starting process for forks

[TehomCD]

While Arx isn't really a framework/library, there's a lot of rough spots for people who try to fork it and get running that I can smooth out. I'm going to keep notes of tracebacks here under this issue for clean databases and address them as I run across them:

File "commands/base_commands/unloggedin.py", line 83, in func

Traceback (most recent call last):
