Support linking of 2D intersection views

* Major refactor from RimGridView to Rim3dView
* Move view linker/controller functions to Rim3dView
* Add bitmask to define the content of a 3D view
* Link views based on matching content
* Enable bit mask operators at global scope
* Make it possible to use 2d intersection views as comparison views
* Fix crash when a view used as comparison view is deleted
* Move unlinking to Rim3dView

* Add options to snapshot only 3D views/plots as part of regression testing
* WBS plot: Improve default name, hide axis for some tracks
