let's have this be size_t?

[MAD, 2017/03/21 19:28:34]

Yeah, I changed it to int because the combobox API we get it from and compare
with is an int, and we get compile errors if we don't static cast it on non
Windows platforms. But now I see that we also compare it to the
std::vector::size() too, so might as well... set it back to size_t... :-/
