[MSO] Minor sql improvements.

PR'ing for MSO since he can't

Commits are atomic and lays things out, so im just gonna paste them here:
 
- 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.
Is this safe if the client goes away?
