Optionally suppress warnings and deprecations when expected.

[workmanw]

I think we may need to optionally (possibly by default) suppress warnings and deprecations when they are expected. This means not invoking the next callback in this addons registered handlers (e.g. asserts/deprecation.js#L14).

I had not done so originally because it felt wrong for this addon to swallow warnings and deprecations without knowing what else could be out there wanting to consume them. But practically speaking, not doing so creates a lot a noise in a test that passes. Example:

ok 166 PhantomJS 2.1 - model-fragments shim module: test the shim modules

Confirm. We should not emit the deprecations that were expected to the console.
