CoffeeScript Base64 implementation

Usage

Base64.encode('hello world') # -> 'aGVsbG8gd29ybGQ='
Base64.decode('aGVsbG8gd29ybGQ=') # -> 'hello world'

But wait, there is more

Also supports unicode strings. Oh wow!

Base64.encode('привет мир') # -> '0L/RgNC40LLQtdGCINC80LjRgOCAgA=='
Base64.decode('0L/RgNC40LLQtdGCINC80LjRgOCAgA==') # -> 'привет мир'
