admin.site.urls autodiscovery doesn't work quite right

[sbuss]

The normal django pattern of admin.site.urls for admin urls doesn't work with baya. I'm pretty sure this is a problem with autodiscovery.

Docs fix: You need to do from myapp import admin as my_admin; my_admin.site.urls at the bottom of your admin.py file. This should be documented, but it's better to fix the core issue.

Long fix: make autodiscovery work properly
