Merge branch 'development' - v0.0.1

First nearly production ready version of the mmio extension

This version delivers basic functionality like checking Input-Pins on
the connected board (see EX9055DM driver) and send error mails if a
pin is zero. Furthermore set LEDs in each flat to either red or green
depending on the amount of energy consumed from the PV or BHKW.
