Fix tests

[locks]

Fixes #23. Fixes #31. Fixes #36. Fixes #45.

I believe this will require a major version bump, as the facepile component had to be removed due to the API being deprecated by Facebook. You can see more detail in the related commit message.
Twitter's share component also got the counts removed.

Thanks @locks ! Just tagging this issue here: #23

Can you also remove the facepile docs in the README?

Will do! We still have some failing tests, I believe due to CSP, investigating.

My attempt trying to debug the issue with failed tests ended up with the following results.

The problems start with:

Ember.$.getScript("//platform.linkedin.com/in.js?async=true", function success() {
       IN.shareHandlerName = shareHandlerName;
       IN.Event.on(IN, 'systemReady', Ember.run.bind(null, resolve, IN));
       IN.init();
});

It loads couple of nasty JS files and one of them (secureAnonymousFramework) breaks the tests:

not ok 14 PhantomJS 1.9 - Global error: Script error. at , line 0
    ---
        Log: |
            { type: 'error', text: 'Script error. at , line 0\n' }

In the browser It'd look like:
Uncaught TypeError: Cannot read property 'Function' of undefined secureAnonymousFramework?v=0.0.2000-RC8.57838-1429&:1033

Going deeper in the code, it breaks on Sslac.Function(...)

At the same time, if you load dummy/app /linkedin/share page, the above script loads properly and hooks Sslac to window object.
Unfortunately, I couldn't find the reason it doesn't hook to window when it's run via ember test -s.

As @anvyst mentions, the manual tests seem to work but not the automated ones. Thoughts on how to proceed? :X
