Fix for getting stuck at receiving version number: read all lines on serial instead of 1 and use for else
set timeout to 0 while reading version number.
set serial timeout to 0.1s
Removed timeout set to 0 in receiving version number again. This breaks readline
fix retries in retreiving version to stop after an answer
do not use serial if the arduino version is not received
changed fixPermissions to use -R for all files, which is a lot faster
use brewpiVersion isntead of avrVersion
removed ser.flush, because it fails if the arduino has not opened the serial port
temporarily increase serial timeout when receiving device values
