Updates & fixes support for iOS target, covers the following:
- Build integration test
- Updates to new kivy-ios structure
- Bumps to ios-deploy 1.10.0 (`make` replaced by `xcodebuild`)
- Makes it possible to toggle code signing (now disabled by default)
Note this is the first iteration of a longer serie.
Subsequent pull requests will try to improve the following:
- code signing process (toggle not fully integrated)
- actual deployment (not yet tested)
- unit tests (mainly `buildozer/targets/ios.py`)
- other forms of technical debt
