Rework browser tests to run in Headless Chrome instead of PhantomJS,
because the latter is no longer maintained.
This allows us to remove transpilation to ES5 via babelify, which
significantly improves speed of our tests.

Fix configuration of Karma:
- Disable ES6 modules. The ES6 module transpiler is adding
"use strict" to all source files, this breaks e.g. chai or juggler
- Relax "ignore" setting to exclude only strong-task-emitter,
thus bring back Babel transpilation for chai and juggler.
Before this change, dependencies in node_modules (e.g. strong-remoting)
were not transformed to ES5 and thus crashed the tests in PhantomJS.
Note that loopback-datasource-juggler cannot be babelified to ES5
because it does not correctly support strict mode yet.
- Remove ES5 parser exception from .eslintrc
- Configure Karma to use Babel to transpile ES6 sources to ES5,
because PhantomJS does not support ES6
- Upgrade es5-shim to es6-shim
Notable side-effects:
- loopback no longer exports "caller" and "arguments" properties
- kv-memory connector is now properly added to the connector registry
- the file "test/support.js" was finally removed
- Move configuration of Karma unit-tests from `Gruntfile.js` to a
standalone file (`test/karma.conf.js`).
- Add a new Grunt task `karma:unit-ci` to run Karma unit-tests in
PhantomJS and produce karma-xunit.xml file that can be consumed
by the CI server.
- Add grunt-mocha-test, configure it to run unit-tests.
- Add `grunt test` task that runs both karma and mocha tests,
detects Jenkins to produce XML output on CI server.
- Modify the `test` script in `package.json` to run
`grunt mocha-and-karma` (an alias for `grunt test`).
The alias is required to trick `sl-ci-run` to run `npm test`
instead of calling directly `mocha`.
- Add `es5-shim` module to karma unit-tests in order to provide
ES5-methods required by LoopBack.
- Fix `mixin(source)` in lib/loopback.js to work in PhantomJS.
`Object.getOwnPropertyDescriptor()` provided by `es5-shim` does not
work in the same way as in Node.
