CWBot

The IRC server receive buffer is now emptied when reconnecting, and the buffer is processed if it ever becomes full. This removes a bug that occasionally prevented cwbot from reconnecting after being kicked out of a busy channel.

The parser in the news broadcast scripts has been
corrected to process the BBC's XML newsfeed
properly.

The URL for the RSS news source, which changed unexpectedly and broke the news scripts, has been fixed.

Some signals watched by the cwbot process were dropped, as they weren't portable, and also could make cwbot die if it was run in an xterm and the xterm was resized. Some includes and the Makefile were slightly modified to allow cwbot to compile under FreeBSD.

A bug that would let internal messages from a channel chat
engine to the bot core slip through and appear in the IRC
channel from time to time was corrected.
