Subject: Discovered that the Bu::Client::disconnect() function didn't do
 anything.  That has been fixed, it now safely disconnects after emptying the
 Client's outgoing buffer.

Added some more helpers to Bu::FString.

Added the beginings of ProtocolHttp using a new method for processing protocols
that's based more strongly on an NFA state machine, this makes sense, but I
never had the desire to actually try implementing it before.  It's working
pretty well.
