Minor edits to files

These commits make edits to AndroidManifest.xml to make it a little more readable, add a .gitignore file to keep development in Eclipse from cluttering the repository, and create a README.md file to present a friendly face to the world, giving someone who happens upon the repository to an understanding what this app does.

I'd also like to recommend changing the description of the repository to better reflect the App's new functionality as follows:
To: A collection of Android Daydreams based on the easter eggs of Android 4.0+
From: An Android daydream based on the Nyandroid easter egg from Android 4.0
