Replace the fixed-size weightsystem table by a dynamically relocated table. Reuse the table-macros used in other parts of the code. The table stores weightsystem entries, not pointers to weightsystems. Thus, ownership of the description string is taken when adding a weightsystem. An extra function adds a cloned weightsystem at the end of the table. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
