[svn] * TODO,src/client.c,src/client.h,src/fetch.c,src/fetch.h,src/noffle.c: Improve error checking during fetches. A fetch is now aborted immediately if the connection times out or if an unexpected response arrives. This should fix problems with articles appearing in the wrong group, and possibly other mysterious happenings.
