-#######->WARNING<-####### Directory structure changed, see commit message

If you use git-python as a submodule of your own project, which alters the sys.path to import it,
you will have to adjust your code to take the changed directory structure into consideration.

Previously, you would put the path
./git-python/lib

into your syspath. All modules moved one level up into the 'git' subdirectory, which means that the 'git-python' directory
now contains the 'git' root package. To allow git to be found, add ./git-python into your path.

To finalize your update, run the following commands

git submodule update --init --recursive

As there will be left-over directories, consider running git-clean
