Get the system stats on the raspberry pi or any linux system in python

GetRaspiStats.py

#This Script needs Python3. Original script from @funvill,
#edit (urllib and http/request support, also added gpu temperature) by @staubgeborener
#This edit allows to post raspberry pi stats on any php supported website. You could use this together with cron for example.
