Initial rewrite to simplify the code structure
error fixes
HerBot.ino now logs Time, Temperature and Humidity and is capable of outputting them again.
Changed the way the log is stored from 5 arrays (of which moisture was a two dimensional array) arrays to an array of a data stucture.
herbot.py selects the first available serial port and reads out the log automatically.
nothing is stored from the python script yet and the time is not resynced
