Added a new enum value to Bu::File, Bu::File::WriteNew which combines Write,

Truncate, and Create, the flags used most commonly when writing a new file.

Also added the Bu::Base64 filter class, it does base64 encoding and decoding,
it may need a couple more interfaces added, but for the most part, it's solid.
