- using the levelgrab(level('./path/to/db') form
  -> seems to be the right way to keep access to level methods
+ Promise.onPossiblyUnhandledRejection handler

- passing tests on ALIASES, ACTIONS, and DB UTILS
- testing on level-test
- fixing the missing reference to CONFIG.root
allowing to change 'env' from command arguments
updating tests with CONFIG.path helpers
