Update .gitignore
Add Stewardship collection UDFs when creating instances
Return stewardship w/ default mobile fields

Because this is adding a new type of field group that the mobile do not
have the ability to render yet, these changes are only available in v3 of
the API.

This is intended to be the final feature in v3, and all new breaking
changes should be part of v4.

Add constraint to InstanceUser to prevent duplicates
Add sort key to default mobile api fields

Because the mobile clients will merge together plot and tree stewardship,
we need to signal to the clients how to sort the merged lists of
stewardship events.

We have no mechanism for changing collection UDF field
definitions at the moment, but if/when we add it this will cause us to need
to take care to not allow the definitions of plot and tree stewardship to
get out of sync
