Andreas Kling 653e61d9cf LibProtocol: Add a Download object so users don't have to manage ID's
LibProtocol::Client::start_download() now gives you a Download object
with convenient hooks (on_finish & on_progress).

Also, the IPC handshake is snuck into the Client constructor, so you
don't need to perform it after instantiating a Client.

This makes using LibProtocol much more pleasant. :^)
