Calmjs-dev

------------------

- Migration to the calmjs-3.0.0 API.
- Bumped a number of dependencies on Node.js packages.
- The paths that are covered by the test coverage report are now
recorded in the Spec as part of the test execution workflow through
the KarmaDriver.
- Provide framework and command for testing of predefined artifacts
generated for packages defined through the ``calmjs.artifacts``
registry; ``calmjs.artifacts.tests`` registry was created such that
toolchain packages may declare the test compliment builder functions
to facilitate testing for their dependent packages.
- Implemented ``--cover-report-type`` flag to support the specification
of multiple coverage report types to be generated, and ensured that
the defined report types actually work (a karma/istanbul bug was
found and a workaround was implemented).
- A number of internal code refactor, i.e. a number of internal API
changes have happened.
- Deprecated ``--coverage-type`` flag, as it is inconsistently named and
that features provided by ``--cover-report-type`` superseded this.
- Deprecated ``--test-package`` flag in favor of ``--test-with-package``
for more clarity about the intention of that flag.

------------------

- Tests are now automatically wrapped by a default template when served
by karma to better limit the scope of the variables defined within
each file. This can be disabled using ``--no-wrap-tests`` flag on the
``karma`` runtime.

------------------

- Move the ``--artifact`` and ``--cover-artifact`` flag up to the main
``karma`` runtime to permit wider and more flexible usage for all
runners.
- Correctly report the path of missing specified artifacts in the logs.

------------------

- Provide test prefix key and constant.

------------------

- Correct the inability to launch standard graphical browsers directly
via the runner under Windows.

------------------

- Initial release of the development support for the calmjs framework.
- Include karma test runner integration as a calmjs runtime that can
accept calmjs toolchain runtimes to facilitate testing.
- Generation of test coverage reports of JavaScript sources executed.
- Leverage the toolchain advice system for adding the test runner and
also permit the modification of test configurations by toolchain
implementations that require specific instructions for a successful
execution of tests.
- Permit integration with other packages for testing artifacts generated
by other systems.
