Reorganize module loading.
We now use webpack instead of SystemJS, effectively bundling modules
into one file (plus commons chunks) for every entry point.  This results
in a much smaller extension size (almost half).  Furthermore we use
yarn/npm even for extension run-time dependencies.  This relieves us
from manually vendoring and building dependencies.  It's also easier to
understand for new developers familiar with node.

/**
* @fileoverview Defines a {@linkplain Driver WebDriver} client for the
* Opera web browser (v26+). Before using this module, you must download the
* latest OperaDriver
* [release](https://github.com/operasoftware/operachromiumdriver/releases) and
* ensure it can be found on your system
* [PATH](http://en.wikipedia.org/wiki/PATH_%28variable%29).
*
* There are three primary classes exported by this module:
*
* 1. {@linkplain ServiceBuilder}: configures the
* {@link selenium-webdriver/remote.DriverService remote.DriverService}
* that manages the
* [OperaDriver](https://github.com/operasoftware/operachromiumdriver)
* child process.
*
* 2. {@linkplain Options}: defines configuration options for each new Opera
* session, such as which {@linkplain Options#setProxy proxy} to use,
* what {@linkplain Options#addExtensions extensions} to install, or
* what {@linkplain Options#addArguments command-line switches} to use when
* starting the browser.
*
* 3. {@linkplain Driver}: the WebDriver client; each new instance will control
* a unique browser session with a clean user profile (unless otherwise
* configured through the {@link Options} class).
*
* By default, every Opera session will use a single driver service, which is
* started the first time a {@link Driver} instance is created and terminated
* when this process exits. The default service will inherit its environment
* from the current process and direct all output to /dev/null. You may obtain
* a handle to this default service using
* {@link #getDefaultService getDefaultService()} and change its configuration
* with {@link #setDefaultService setDefaultService()}.
*
* You may also create a {@link Driver} with its own driver service. This is
* useful if you need to capture the server's log output for a specific session:
*
* var opera = require('selenium-webdriver/opera');
*
* var service = new opera.ServiceBuilder()
* .loggingTo('/my/log/file.txt')
* .enableVerboseLogging()
* .build();
*
* var options = new opera.Options();
* // configure browser options ...
*
* var driver = opera.Driver.createSession(options, service);
*
* Users should only instantiate the {@link Driver} class directly when they
* need a custom driver service configuration (as shown above). For normal
* operation, users should start Opera using the
* {@link selenium-webdriver.Builder}.
