Several OpenMP improvements

Several optimizations based on profiling of 20M grid model. These fixes will improve the largest performance issues, but there are still more operations that can be refactored.

* OpenMP: Use in fault geometry generator
* OpenMP: Use when computing statistics for result values
* OpenMP: Use multithreading on fault detection
* Add RiaOpenMPTools
* VizFwk: Use openMP for texture generation
