Improve grid cell calculator

* Use full name for grid case view
* FIx signed / unsigned issue
* Support drag/drop of file names into Main Window
* Add function to check if two grid cases are of equal size
* Result Info: Show cell result text for all linked views
* Improve how to specify cells to be included in calculation

- move view filter to calculation
- improve how to assign values to non-visible cells
- avoid computation between grids of different size

Closes #9482
