Adjustments fault distance calculations

[magnesj]

The performance of the fault calculation is blocking the ui for 20-30s for larger cases. Several UI adjustments are suggested:

• create a folder Data Analytics inside a grid model above the first view
• in this folder, show objects like Fault Calculation and Well Target Mapping in a flat list
• Fault Calculation adjustments
  • rename object to Fault Calculation
  • do not recompute when changing selection of faults
  • add a button Compute to trigger calculation
  • add progress bar to the fault calculation operation
  • show text in the Fault calculation object explaining how to visualize the result
