Splitting library into own file. Adding onewire.

The mqtt.c file was getting pretty big, so the example code
is now in main.c. Also, we need a onewire library, so I've
started to write on in onewire.c. We will need to make some
changes to the Makefile as well, but I will need to consult
a couple of resources for that.
