hotfix for mac-detection and various variable names (#139)

* Change Client-Name: The client name inside LVA is not capable of having spaces in the name. Fixed the example.
* Add first version of Docker-Compose for developers
* Add variable for network-interface and auto detection by default
* Added autodetection for the MAC-Address based on the detected or specified network-interface.
* Switched from listening on all IP-Addresses to the IP of the default interface, usually u set the correct network-interface and it will automatically detect the right IP-Address.
* Added missing variables, fixed variables names
* Fixed not working variables for example sound-files.
* Moved the auto-name creation from shell to python. The name is no longer mandatory, it will be generated if no name is given.
