Documentation: defaultLimit global config option is missing

[campfire-git]

Spent a bit of time wondering why this wasn't respecting the default limit of feathers service backend.

After looking through code repo, found out that feathers pinia config needs the defaultLimit option to match what is in the backend or it will send $limit=10 when no limit is supplied.
