Removes extra sql sanitize procs in favor of sanitizeSQL()
Removes some sql related lag caused by too many clients connecting at once after a restart
(and other minor fixes to client sql logic)

Clients will now spread out their sql database connection logging and related ckey by ip/cid searching at world start so it doesn't all happen at once.
Fixes a minor bug with related ckey searching where only one would be returned.
Fixes a minor bug where related ckey searching would return the client's own ckey.
Feedback reporting now uses 1 insert query with mutiple rows
Rather then making a new query for each feedback item.
Each query can take between 25ms and 100ms, and this is a static per-query overhead, so removing the 60 or so needless querys will speed things up.
Ensures spawned proc is never called if the client goes away
Fixes admin only vv related sql injection exploit in feedback reporting.

Noticed this while looking over my PR, by storing (and trusting) the escaped version, an admin could edit this in vv and do unspeakable things to the database
