Use std::to_string when doing ascii conversions

Browse source 
It's fast, it works, it's correct. No need for
any of the fancy stuff when all we want is int
to ascii string.

Currently on my system the implementation of
std::to_string is *very* similar to mine, but
it doesn't have the overhead of calculating
ASCII offsets because their lookup already
contains ASCII values.
