1249 - new type: index_t

It will always be identical to size_t, just more readable, like
recipe_number, etc. The various unsigned types are sizes, indices (which
often compare with sizes for bounds checking), numbers which are
canonical elements of a specific space (like recipes or mu types), and
ids which I haven't introduced yet.
