- updates all imports to prefix kivy_ios
- adds basic `setup.py` file
- adds a simple `toolchain.py` to the root folder for compat
Makes it possible to install kivy-ios from PyPI:
```
pip install kivy-ios
toolchain --help
```
Note the `rebuild_updated_recipes.py` is expected to fail as we
moved all the recipes.
This is a working, but unperfect iteration that come with limitations
we would address in subsequent pull requests, such as:
- the new usage is not yet documented
- CI is not testing the source distribution creation and install
- Continuous Delivery to PyPI is not in place
- `toolchain` binary is a bit too generic name
- we're still vendoring things under `tools/`
When I attempt to push my app to the app store, having the resource rules path populated causees this error:
ERROR ITMS-90339: "This bundle is invalid. The Info.plist contains an invalid key 'CFBundleResourceSpecification' in bundle mingyu [mingyu.app]"
According to this post...: http://stackoverflow.com/questions/32504355/error-itms-90339-this-bundle-is-invalid-the-info-plist-contains-an-invalid-ke
...Deleting the code signing path solves the issue. This does in fact resolve the above error and I am able to push my app to the app store if I do this. So, I am proposing it be changed in the toolchain as well.
