Setting a taxonomy category was cumbersome: the caller had to make sure that the category-table was allocated. Introduce a helper function to make that simpler. Make taxonomy_set_country() the first caller of the new function, since it is just a special case with category = TC_COUNTRY. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
