Added love.math.encode(format, data | string [, linelength]) and love.math.decode(format, data | string). Current formats are "base64" and "hex". The optional line length only applies to base64 and specifies the maximum number of characters per line in the encoded string.

Removed the variant of love.filesystem.newFileData which decoded a base64-encoded string since it's redundant.
