[RFF] Use ground:db by default

Bake in data caching by making Ground.Collection the default instead of Mongo.Collection.

This would mean using ground:db.

Pros:

• Data is cached on the user's browser, making initial load times look a lot faster for repeat visits
• Very transparent, works exactly like the Mongo.Collection if you don't want to look into any of the special features that Ground.Collection gives you.

Cons:

• The caching capabilities of Ground may not be necessary for all projects
• Bloats a project with additional technical debt
