New serialized object, public key, and private key interfaces

Browse Source 
This introduces functions get and set, and a family of specialized
structs called STExchange. These interfaces allow efficient and
seamless interchange between serialized object fields and user
defined types, especially variable length objects.

A new base class template TypedField is mixed into existing SField
declarations to encode information on the field, allowing template
metaprograms to both customize interchange based on the type and
detect misuse at compile-time.

New types AnyPublicKey and AnySecretKey are introduced. These are
intended to replace the corresponding functionality in the deprecated
class RippleAddress. Specializations of STExchange for these types
are provided to allow interchange. New free functions verify and sign
allow signature verification and signature generation for serialized
objects.

* Add Buffer and Slice primitives
* Add TypedField and modify some SField
* Add STExchange and specializations for STBlob and STInteger
* Improve STBlob and STInteger to support STExchange
* Expose raw data in RippleAddress and Serializer
