N°3136 - Add creation and modification of n-n objects in object details (#378)

* Rebase onto develop

* Use exit condition instead of englobing condition

* Add informative modals that can be called from modal toolbox

* Refactor "apply_modify" and "apply_new" into own controller, handle ajax requests with a json response and handle these responses in linkset creation/edition

* Fix merge issues

* Remove inverted condition

* Move linkset create button to a better place, still needs to fix duplicate "New" button caused by a refactor

* Handle "Cancel" button in modals

* Do not display relations when editing an object in a modal

* More elegant way to add "New" button to relations lists

* 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

* Rename event

* Rename extra param

* Add phpdoc

* Revert changes

* Check indirect linkset rights before allowing creation in modal
