Visual upgrades and informational improvements

Good evening, @PrivacyCollective! Since I am probably one of the few folks who is still very eager to hack up this API and see it being merged into AOSP, I've done you a favor and beautified your repository a little and fixed a few things. This will not only make things more clear to contributors, but also give some eye candy.

Also, would you please change your project description to the one I have set like below (or see my fork)?
` Ciphering Indicator API for Android! - https://code.google.com/p/android/issues/detail?id=5353`
This is essential for people searching for the Ciphering Indicator on GitHub since the crawler uses this.

Hope you like my small contribution and **never give up** on this wonderful attempt. Cheers! :beers:
