mp meta repository ready to run setup.py

Hi

I just wanted to let everybody know that the meta repository [1] is now ready
to be used for development and release purposes. It contains a setup.py
calling all git submodule setup.py files used for generating a MediaProvider
software installation.

*Todo*

Most files from "data/settings" will be removed soon and placed as template
files under "_developer" in each submodule and under "data/settings" in the
meta repository to contain safe default settings files.

Best regards
Tobias "NotTheEvilOne" Wolf
