Steps to reproduce:
1. Process many workflows
2. Go to /episode/episodes.json?limit=0
The REST docs specify that a limit less than one is 'unlimited'. What the logic does (in multiple places) is refuse to set values less than one, or throw exceptions.
A list of all of the episodes in the system
After removing the code that refuses values less than zero, setting a limit of zero appears to work properly in that it returns zero results. We should remove the inaccurate documentation.
