OPENAM-6347 Automatically logout XUI "users" to login page, admins still use session expiry dialog

AME-9016 Update Karma to use Mocha Reporter

Replace QUnit with Karma/Mocha/Chai Karma provides a web server for hosting the tests, which removes the requirement for an application server to deploy to. This makes it possible to easily integrate the unit tests into the build. It also watches the source files and automatically reruns the tests. Mocha and Chai provide a modern testing experience, with a BDD testing style and comprehensive assertions. As part of this change, the QUnit tests that were functional-style tests have been removed. The plan is to eventually replace them with true functional Selenium tests.

AME-8327 Move the majority of build tasks from Maven to Grunt A JavaScript build process is more manageable and is compatible with far more JavaScript tooling than the existing Maven process. As an added benefit, Node.js executes the build an order of magnitude faster than the Java-based Rhino runtime. In order to provide a version of Node.js for the JavaScript build to use, this change introduces the use of frontend-maven-plugin, which downloads and executes Node.js. Maven is currently still responsible for the unpacking of the project dependencies and the packaging of the final artefact. The only change in behaviour in this change is the replacement of JSLint with ESLint. This is because the version of JSLint used by the Maven build was 2011-03-07, which is not supported by the grunt wrapper.
