macOS beta, Python upgrade

I had to update to Python 3.7, as this is version that is normally installed on Mac when you use home brew, version 3.6 is no longer found as an installer on python.org as well. If Python still doesn't work, I added a python kill switch with the environment variable ORM_NO_PYTHON to be defined before launch.

Additionally fixed the bundled adaptions problem, they should now work out of the box.
