Replaced instances of resize&memcpy with append, which gives a noticeable performance boost.
fr::Packet::operator<<(const char *str) no longer converts str into an std::string before adding it, removing an unneeded copy.
fr::Packet::clear no longer calls erase, should result in more of the internal buffer remaining allocated.
Framing for std::vector's has been changed from a uint64_t to a uint32_t (breaking change for packet framing!)
Added Sha1 hash, and Base64 encode implementations which are optionally compiled if websock support is enabled, to assist in the WebSock handshake.
Added WebSocket to manage the WebSock protocol during connections.
Added WebFrame to allow for sending/receiving data through the WebSock protocol easily.
