Nadav Har'El 5b071fd224 sstring: support to_sstring() for floating-point ...

std::to_string() can also convert a floating-point argument to string,
using the "%f" printf format (see
	http://en.cppreference.com/w/cpp/string/basic_string/to_string )
So add this support to our to_sstring() as well.

Note that if you want to use a different format, e.g., "%g", you can,
by using the to_sstring_sprintf function, for example

	to_sstring_sprintf(12345678.9, "%g")

results in "1.23457e+07".
