RaspberryWifiRouter v1.5

The old release of the router was built on top of Raspbian Wheezy.
The whole software has now been upgraded to work on Raspbian Jessie.
This includes the service management with systemd.
Parts which are not completed or have errors are now hidden in the software.
Future releases will be compiled to add functionality and/or fix bugs.
