* Rebase onto develop

* Factorize vertical highlights in alerts and modal in a single mixin

* Replace button name with dict entry code

* Change route name to snake case

* More elegant way to add "Create in modal" button to relations lists

* Replace triple if with in_array

* Move listener to body

* Rename variable to match boolean rules
