Add ATmega32U4-compatible Arduino as ISP programmer

Use of the stk500v1 protocol for Arduino as ISP does not work with native USB boards on Windows. The arduino protocol does.

However, the arduino protocol makes it more likely that boards with an external USB interface chip will require the auto-reset circuitry to be disabled to allow them to be used as Arduino as ISP. That adds extra complexity to a process already difficult for the average Arduino user.

For this reason, a new programmer using the arduino protocol is added specifically for using native USB boards as Arduino as ISP and the previous Arduino as ISP configuration is retained for use with all other boards.
