Update project with entry save.
Update project with entry save.

This done using the project select list's `selectedIndex`. This assumes that both entry.parent.projects and the index begin from 0 and increase by one for each entry. Theoretically this shouldn't be a problem, but I would prefer a solution using something explicit (e.g. project.id).
