[Feature Request] Add "Sort by stack size"

[Xelloss-nakama]

It would be great that when we stack comics we could order the stacks by stack size (number of comics in the stacks)

Nowadays comic stacks can be order only by comics fields, but not by stack properties such as the number of comics included in each stack (another fields could be max number, min number, etc)

I would like to see this also.
