Patch for decoding a base64 string to a Unit8Array.

[GoogleCodeExporter]

The attached patch adds decodeStringToTypedArray which decodes a base64 string 
to a Unit8Array.

The function is based on decodeStringToByteArray with two changes:
1. We need to calculate the outputLength and initialize the typed array:
var output = new Uint8Array(outputLength);
2. We need to use 
output[outputIndex] = Byte;
instead of
output.push(Byte);

I've also added Uint8Array as an optional type for 
goog.crypt.base64.encodeByteArray input param.

Thanks
