Using blas for HGH pseudopotentials. This improves the performances, especially for SOC.

merged

Some tips:

• For better performance you might want to use level 3, or at least level 2 BLAS functions. These ones perform much better than level 1 ones. This is why I merged the application of all projectors

• You can use blas for complex functions, you just need to call the real version with double the size. (You might have to use an implicit interface.)

Thanks for the tips, this is good to have a feedback and good advices. I will test that latter.
