nightwatch-extra does not support Nightwatch 1.x

[rsheldiii]

When upgrading to nightwatch 1.0.0 or subsequent, the new api loader does not like the current way the testarmada assertions are written. I get this error:

The assertion module needs to contain an .assertion() method

which seems to come from here: https://github.com/nightwatchjs/nightwatch/blob/b3e1e1846ccabe806f54ab2bd8821b55e4e425ce/lib/api-loader/assertion.js#L43-L47

which suggests that instead of exporting the entire class, if the assertion files just exported the assertion function as module.exports.assertion, this would work with Nightwatch 1.x

In addition to the above issue with assertions, plugins (appium / dictionary) don't appear to load, either.

In addition to the above issue with assertions, plugins (appium / dictionary) don't appear to load, either.

In globals, plugins can no longer access this.test_settings which defines extra flags for Appium.
