Simplifying tests of nlisomoisture material.
Added timeScale parameter for vtkXML output.
Adding string literals for every input record into each respective header file. Strings are not actually checked to be correct yet, but were automatically generated from the last part of the input record (which fits in most cases).
Merge branch 'master' of www.oofem.org:/data/git/oofem
Correcting tests results for concrete_3point_direct to match new convergence check in nrsolver (very small difference that casued the test to fail)
