Renames, stability changes

Rename traits that are too long, make changes to stability levels
More stability changes

The stability traits are still meaningless for now, I need to do this

New implementation of fragmented messages

This is much more friendly than the other implementation, also add an
HTML example
Version 0.9.2

Changed fragmenter
Fix example: Pong -> Ping

Typo fixed
Version 0.9.3
Set a WebSocketProtocol to keep Chromium happy

Shouldn't need this according to RFC6455 Section 1.3:

The server selects one or none of the acceptable protocols and echoes
that value in its handshake to indicate that it has selected that
protocol.

Should be able to select none?
Fix server pong
Version 0.9.4

Update to latest Rust

Send is now unsafe
