Enhancements compared to current official version

• A bug causing too low intensity values when using the "Counts" scaling of the diffraction pattern has been fixed.
• Another bug that affected the number of CPU cores to be used for profile fitting search-match has been fixed. This bug could cause the profile fitting search-match not to work at all on machines with very few CPU cores or on virtual machines.
