It expected to be used in 2 case: some gameevent must send mails at start/end,
and this can be useful in game commands. Both case wil implemented in later commits.
* New MassMailMgr can accept tasks for send mass mails in safe way for map update threads context/etc.
* It work in way:
- By provided race mask or more generic SQL query string in async query selected affected characters
- At query result ready at next world tick update in safe common part of tick code some from mails
from queued mas mail tasks send.
- Amount mails limited MassMailer.SendPerTick confir option (10 by default). This done for prevent
high server load/lags at send too many mails in one tick (mail send all existed characters in DB
who match to seelction criteria)
- Manager not persistant for server shutdowns so any not send mails in queue lost at shutdown.
But with default setting 10K mail send in 20 secs (10000/50/10). Adding more safe execution
for this case will make related code lot more slow and req. many DB tables and code support.
* Use Set* names for cases when function replace old value by new (instead Add*)
* Prevent hidden MailDraft copy create becase if draft have items its can't be just shared
and need preoprtly cloned, but item close is high price operation (guid use, DB tiuched and etc)
So this must be explictly operation. In next commits will be added clone function for this.
* Some MailDraft overwrite by assign cases rewrited to more clean way.
Also
* Use typename for mail item info vector.
* Include tools/characters_mail_items_cleanup.sql for cleanup lost mail items.
It also included as sql update part. Sql update also fix receiver for stored
in DB expired mail items.

Also
* Fixed some amount wrong uses low guids as full player guids.
* Add private without body ObjectGuid(uint32 const&) for catch wrong assigns low guids to ObjectGuid.
In some cases need assign "0" guid, then use ObjectGuid() instead.
* Fixed .pdump commands work.
* Avoid use explicit MailReciever/MailSender where not need.
Types specially added for autoconvertion from common cases.
* Prevent allow copy text auction mails. It anyway store encoded data.
Same for some another non-player mails.
* Move send functions to new MailDraft class from WorldSession
* Simplify use different args combinations used in SendMailTo
by groupping its by functionality in Helper classes. This also will prevent wrong way use args combinations.
