Add print(signed char | short | float) explicitly
Add explicit print() support for signed char, unsigned/signed short, and float. Also, add `signed` keyword explicitly to int and long (even if unnecessary). Notice that `char` and `signed char` are considered different types, even if their ranges are the same (ditto for `unsigned char` in SAM). Both AVR and SAM seem to define [u]int8_t explicitly as [un]signed char and not as char, so printing them will print them as numbers as expected. (This does not apply to `int` and `signed int`; those are the same type.)
