HTTP and streaming

I've made some big changes to my HTTP code. HTTPParser no longer waits for the end of a response/request before sending information about it on - it now follows the format:

• HEADER
• BODYCHUNK
• BODYCHUNK
• ...
• BODYCHUNK
• END

This allows memory to be saved and lower latency processing. As a result of this modification, my HTTP client now allows HTTP streaming.

My HTTP client has also been refactored to support this change - it is now split into a SingleShotHTTPClient which handles a single URL before terminating and a SimpleHTTPClient which uses the SSHC with a Carousel component to handle several requests one after another. I've also added a Kamaelia component called IcecastClient which can stream MP3 audio from a SHOUTcast/Icecast server. As the SHOUTcast protocol is almost identical to HTTP, this component subclasses SSHC.

Documentation will be my next focus.
