Initial draft of Base64 encoding in JavaScript guide.

[JeffreyNovotny]

I wanted to include a table demonstrating the encoding process , but because the different rows had different numbers of fields it does not work as a Markdown table. I added the information as a file, but feel free to convert it to a better format if you can think of a different solution.
