Optimize reading and writing for the STK500 programmer if the part

supports paged reads and writes.  This greatly decreases the
program/verify time from about 4.5 minutes down to about 10 seconds in
a 12K program size test case.

Print out the hardware and firmware version for the STK500 if verbose
is enabled.
