[svn] * src/group.h,src/group.c,src/noffle.c,src/server.c: Grp_setLastAccess is only ever called with last param as time(NULL), so remove it and call time() inside the implementation of Grp_setLastAccess. * src/client.c,src/group.h,src/group.c,src/noffle.c,src/post.c: Groups are automatically unsubscribed when the last access to the group is older than a particular threshold. However, for very low traffic groups, the last access may exceed the threshold simply because there has been no new article posted. In this case, rather than unsubscribe, update the group last access time. This means that groups are now only unsubscribed if the last access exceeds the threshold AND articles have arrived in the group since. Add Grp_setLastPostTime() to track the last time an article arrived in the group.
