Removes ARDMK_PATH, ARDMK_FILE and arduino-mk subdirectory
Looks for ard-reset-arduino in $PATH or ARDMK_DIR/bin
Fixed git-archive command in RPM SPEC file
Kept Common.mk - AUTO_ARDUINO_DIR still works
Upped version to 1.2.0
Removed some whitespace
Updated docs
Also removed arduino-mk dir from debian package's arduino-mk.install
