Przemo Firszt a46e8c3129 FEM: Change default behaviour of ConfigParser used for materials 
ConfigParser changes option capital letters in keys to small letters.
That commit changes it to generate verbatim keys as read from FCMat
files. Also Section names are no longer used to generate material
dictionary.
