See https://hub.docker.com/api/audit/v1/action/05620acd-9984-4e10-9053-3a7edc0c8558/ :
```
The command '/bin/sh -c npm link && npm test && rm -rf /tmp/nativefier* ~/.npm/_cacache ~/.cache/electron && chmod +x $NPM_PACKAGES/bin/nativefier' returned a non-zero code: 243
```
Culprit could be `rm -rf /tmp/nativefier*` : at this point /tmp/nativefier
doesn't exist, so `sh` cannot evaluate glob `/tmp/nativefier*`, and exits 1
- Docker builds for Windows are fixed (fixes #997)
- Switched over to use Alpine (as was indicated as desired in https://github.com/nativefier/nativefier/issues/375#issuecomment-304247033) - which may mean #375 is fixed as well.
- Fixed bug where Docker has the wrong line endings when copying from a Windows host
- Fixed the invalid `arm` arch to `armv7l`
- Add `npm t` to the docker build to ensure tests pass before we start trying to do builds
- Add a message to help the user when trying to build Mac apps on Windows as a non-Admin (currently an unhelpful exception)

TODO: windows are currently not possible, because of non 64-bit version of `node-rcedit`, see https://github.com/electron/node-rcedit/issues/22. Also there is currently no 32-bit alpine package for wine, what possible solve this image.
