Move reseting Leonardo logic to ard-reset-arduino

ard-reset-leonardo which was used for reseting Leonardo was written in
Python. Now the logic is added inside the ard-reset-arduino perl script
itself.

Fix #62

commit c798eb26ea
Author: Simon John <git@the-jedi.co.uk>
Date:   Fri Jun 14 11:10:12 2013 +0200

    replaced ard-reset-leonardo with an update to ard-reset-arduino
    which is now called from Arduino.mk with the --leonardo flag

    removed some trailing whitespace

    upped version string in Arduino.mk
