Fix mistakes of treating of magn.moment of real particles in case of presence of MAGN_ANISOTROPY properties and inactive magnetic_anisotropy constraint
Add test script for a magn.anisotropy case
Included magnetic anisotropy testcase into testsuite
1) Includes to the documentetion (file part.tex) description of magnetic anisotropy
2) Adds test on the thermaequalibration of the ensemble of magnetic particles with random distribution of easy axes
Merge branch 'mag-aniso' of git://github.com/Petr-Melenev/espresso-dev into maganiso-release
