Link books that belong together and show them together

[ajl789]

Is your feature request related to a problem? Please describe.
Books belonging to a series dont show up together in the view.

Describe the solution you'd like
There should be a possiblity to link books that belong together. Maybe an optional field could be added like "Part of" or such. This way the user could sepcify that certain books belong to a certain series/collection. Then in the view of all books those that belong together could also be shown together. For showing the books in correct order another optional field like "Number in series" could be added. This way in the book detail view the next/previous books of the series could be shown as well which would enhance the user experience.

Maybe a tag could be used for this that goes like part-of:[${COLLECTION_NAME}]. That might be simple solution. And then books with the same tag of this form should be shown together.

It would be very useful to support series, with the series/collection name and optionally the index.
