consider improving structure of code repository

the code repository here contains both the plugin itself and a bunch of other stuff - ideally it would be good to split this out and make the plugin code inside the "root" of the git repo so that people can install this plugin as a git submodule or subtree - at teh moment they have to extract the files and manage them manually instead of being able to use git properly to install a plugin in their site.

also - you might want to consider using an easier location for your git repo like github/bitbucket/gitlab.com.. Creating an account so that I could login here was possible, but not what I would call an easy process - especially for someone that doesn't speak German! :-)

Note: We don't require this for approval in the plugins db - as long as people can login and report issues like I'm doing here, but if you're interested in community contributions to your plugin then it might foster more contributions being in a more public/easier to access git repository.
