Better collection pages including more view options (#1137)

## Description
This is a large update to the collection page!

- Show the collection's details including overview & backdrop
- Separate collection by type (Movies, TV, etc) into rows
- View options are now shared across all collections
- Filter & sort are still saved per collection

By default, the collection will be separated by type, but there is a
view option to restore the combined grid.
