Fix: notifications (fix #88, fix #956), processEnvs, using as git (#955)

1. Fix (broken since 2016): Notifications broken by lambda constructor
2. Fix: `--processEnvs` broken by additional processEnvs object, the result was:
`processEnvs: {processEnvs: {...}}` which caused the conversion of the inner object into string `[object Object]`, no nesting allowed there probably. Compatibility introduced.
3. Fix: package.json missing `prepare` (or even prepublish), which breaks using as git dependency.
