ard-reset-leonardo perl replacement (fixes issue #62)

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 

deleted ard-reset-leonardo python script

merged with the #70 libs directory fix so will pull cleanly
