Add split functionality into ircd
Add /split command
Add /stats S/split (make /STATS s/S case sensitive, s spoofhosts)
-Add feature SPLIT
+Add feature SPLIT HIS_SPLIT
Add split.c split.h m_split.c
+Add SPLIT priv
+Add LS_JUPE for logging
NOTE: feature SPLIT is default enabled as that is just easier when working on this patch.
