* Remove dead code

* Add before/after sleep delegates

* Remove pin turn stable state setting

* Make hardware messages mysensors alike

* Enable route size reduction for devices with smaller eeprom

* Add macro for routes size to keywords

* Fix keyworkds.txt - using tabs instead of spaces

* Remove tinyAVR hardware debugging

* Remove unused macros

* Remove .history folder

* Fix formatting according to astyle

* Remove unused count variable

* Update MyTransportHAL.cpp
