Reorganize Git interface scripts
Move the Git interface scripts from git-interface/ to aurweb/git/. Use setuptools to automatically create wrappers which can be installed using `python3 setup.py install`. Update the configuration files, the test suite as well as the INSTALL and README files to reflect these changes. Signed-off-by: Lukas Fleischer <lfleischer@archlinux.org>
