Simplify the book creation form
There are too many fields ont the form. They are all useful but to simplify the creation of a book but we should display the bare minimum to simplify the form. A few ideas :
- the user language should be selected as default. There are great chances a user will create books in his / her own language. Maybe the language should not be mandatory.
- remove unnecessary fields : Linked to issues #570 and #574 (closed)
- the user should have an advanced section hidden by default that would contain all non essentials fields : Série, Sous-titre, Maison d'édition, Description
Note : all forms would need to be simplify (in the mediacenter to create a media for instance), but this is a larger UI project.
