Possibility to edit/ delete collections

[DylanGomez]

When making collections, once the collection is made it can not be edited or deleted by the user.

Images and video are default. Custom collections are not visible anymore when there are no items left in that collection.

Editing a collection name is not something we'll focus on, currently.

Feel free to create a pull request if it's a strict requirement for your project.

Otherwise like Robin said, the collection will be removed from Nova if there's no media left in the collection.

For now I will be closing this issue as there is no issue.
