memory improvement of the print.cpp lib

Many functions in the print.cpp lib use a int base as second argument. As bases above 255 are never seen all these params can be brought back to uint8_t base.

Furthermore the #digits for the printing of floats can also be an uint8_t

When testing a sketch it uses 14 bytes less (from 2006 bytes to 1992 bytes)

As print is a base class for several other classes this adds up.

Might be done together with other print.cpp fixes like - Issue arduino/Arduino#884 -

Posted some additional memory improvements of the print.cpp in the printNumber() and printFloat() in the thread mentioned. Together these remove >300 bytes from the print lib.
