#465 Aquarii End August Cleanup

Final stages just going to list the remaining to be done fixes here: - Memory leak on send mail addressed when target player is not on server at time of mail being sent. - Removed old MISC TODO logs and functions that were not relevant, already completed or had other alternative options (code, lua, otherwise). - Additional comments or commented code that were not needed any further - /trade reject now just calls trade cancel (same thing right?) - EmemJR: fix level display for item recipe requirements - Fixed city zones not initiating shutdown when clients leave after a bootup (keeping a zone up always is reserved for always_loaded flag)
