v0.6.1

This release has mainly improvements in error handling. It is now again possible to receive detailed logging messages using the --no-silent option. Furthermore, the deployment is aborted if the previous build fails (thanks to @masaxsuzu).

Fixes

• fix: monkeypatch util.debuglog() for extended console logging (08d05c9)
• fix: use callback to retrieve error message of gh-pages (6a8a3c2, fixes #74)
• fix: throws an error if app building fails (e7f6a51, see PR #85 which fixes #74)
