Here is the situation for this patch.  In Eggdrop 1.1+grant, join
protocols are sent as join <bot> <nick> <channel> <flag><socket> <host> while
in 1.0x they are sent as join <bot> <nick> <channel> <flag> <host>.  Because
1.0 bots don't expect there to be anything after the flag character, when it
relays the join command to all the other bots, it sends it out as a 1.0
protocol, so if it received a 1.1 protocol, the socket got stripped.  This
meant that 1.1 bots on a botnet connected through a 1.0 bot wouldn't be able to
communicate properly since the part protocols were sent as are because the part
protocol has the socket at the end.  This patch fixes the 1.0 relaying of
join protocols so that 1.1 protocols are sent out properly.  If you don't have
any 1.1 eggdrops in your bot net, then you don't really NEED it, but if you do,
I strongly suggest it because the other 1.1 eggdrop will be registering users
that have left for at least the next 24 hours.
