Feature/dynaconfig

Hi,

I'm just starting my first build of brewpi at home, and since I've no available windows OS there, I've set up a Makefile to build both for uno or leonardo on linux using avr-g++

needed package are :
# sudo apt-get install arduino avrdude arduino-core avr-gcc

It seems to compile correctly. Unfortunately I haven't received my arduino yet, so I need to run some more tests to validate the environment. But I think it could be usefull to linux users

All the best,
Julien Mottin
