8 update from 7.0

intial refresh PR before PR on modules
moving in `__unported__` folder is to say clearly it isn't ported thus we won't check pep8 and pylint it.

and setting to installable to False is to say in current state it doesn't work so a user downloading this repo won't be able to install it even though he adds a symlink.

It was part of migration procedure: https://github.com/OCA/maintainers-tools/wiki/Migration-Launchpad-%E2%86%92-GitHub under "Set all the modules of the 8.0 branches to "installable": False"

I would prefer to have all repo at the same state.
