tdf#115007: add NatNum codes for cardinal/ordinal number names/indicators

... based on libnumbertext integrated since commit
f1579d3d6c5f5f3a651825e035b93bee7a4f43c6.

[NatNum12] gives cardinal number names (one, two, three, ...)
[NatNum13] gives ordinal number names (first, second, third, ...)
[NatNum14] gives ordinal indicators (1st, 2nd, 3rd, ...)
