Title: [slugable] users can set updatable to false and get "editable" slugs with auto generation on empty slugs

I have improved a bit behavior of the Slugable fields.

Our clients want to have ability to edit manually slugs and generate them automatically, when slug is empty.

Right now when I set updatable=false , slug is not generated even when its empty, which is not good.
Also, when I set updatable=true it doesnt guarantee, that slug always build based on needed fields - some user
can change slug directly in entity.

So, I have improved a bit behavior of the slugable - users can set updatable to false and
get "editable" slugs with auto generation on empty slugs.
