Add handling for different encryption keys for the stations
There are eight key files in the common folder. The files are converted
to header files on compile time and the array of the keys is filled with
them. After determining the device id via the pin programming the
corresponding key is chosen.
Each of the keys is
mapped to one station id.

Add handling of the salt
On start-up the sensor sends a Get_Salt-message to the base station. The
base station responds and sends the salt, which the sensor uses from
there on.

Generate an ID according to the dip switches
The ID is used as the last byte of the RX address. It is also sent as a
part of the data packet to allow assigning the sending station to a
packet.

Add prototyping code for sending a dummy message with the nrf24l01
The firmware is developed using an aduino micro pro with an atmega32u4
as the hardware for the weather station is not ready yet.
