/src/modules/third/hyb-statsconn.c

Shows RPL_STATSCONN upon client connection and when LUSERS is called. Doesn't add a lot of value otherwise, but I like how it shows how many actual IRC clients (as opposed to all accept()s in /STATS T) have connected to the server during the current run. I named it hybrid-statsconn since that is the first time I remember seeing this information, but I don't know where this numeric really came from. Oh well :)

[22:56:45] * There are 6 users and 410 invisible on 147 servers

[22:56:45] * 129 operator(s) online

[22:56:45] * 218 channels formed

[22:56:45] * I have 4 clients and 1 servers

[22:56:45] * Current local users 4, max 6

[22:56:45] * Current global users 416, max 1000001

[22:56:45] * Highest connection count: 7 (6 clients) (26 connections received)

(These were the stats after running for about two weeks without a reboot in the round robin)

Adds +q to the user who creates the channel. Not super useful but InspIRCd used to have a feature like this - especially useful if you do not have services like PissNet. Very simple, possibly a better way to accomplish this but it works for me.
