Improve well path modeling

* Improve handling of MD at first target
* When sea level well target is disabled, update MD of first target
* Show well target spheres by default, allow toggling of spheres
* Activate well target modifiers when clicking on well targets
* Remove selection update causing an unstable 3D view
* Improve display and handling of multiple locations
* Add special 3D target for tie in well target
* Add slider to tie in MD input field
* Show MD in well path target table
* Delete all well path laterals when deleting a well path

* Python : Add lateral to parent well
* Python : Add perforation interval
