js: Added browser testing for unit tests

--

* Added unittests to be run inside a Browser. To be able to access
  the non-exposed functions and classes, a testing bundle will be
  created, containing the tests (unittests.js) and the items to be
  tested.
* src/Helpelpers, src/Key, src/Keyring: fixed some errors found
  during testing.
