* Player's knockback movement now smooth and doesn't looks like teleporting
* Cleanup WorldSession::HandleMovementOpcodes, separated opcode specific and generic movement handlers code
* Handle Feign Death aura interrupting into more appropriate place
This meaning that ObjectGuid only proper way create guid from lowguid now.
But packet handlers still generate uint64 guids. Some DB fields also loaded uint64 values.
Also possible existed not catches et uint32->uint64 assigns.
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.
After this commit auction auctioneer guid used only for select auction house in packet or loading.
Next task replace it in DB by houseid, dependence DB data from creature guid isn't good.
Maybe command not so useful for stable case because spell can be learned,
but it example how can be packet allowed depndent from player possibility
when some functionality base at many packets recieved from client.
Same way possible can be used for auction anywhere, maybe some other cases.
Also it will very usefull for 2.x/1.x branches where no another way... ;)
Some opcode handlers have many code with possible deep calling
far teleports by some reason (death, quest script, etc).
This can be triggering unexpected lost Map context and crashs result.
Note: player login opcode still have disbled delayed teleports (old way work)
just becase Player object created in it and not have flag set.
Calling point look not 100% safe but at this commit this way not chnages for while.
* 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.
* Base at TOM_RUS reseach save/load character specific account data in new table `character_account_data`
* Move its in sql update from `account_data` to new table.
* For client packets that can be send in loggined state or just after logout but assocualted
with recently logout character add new login status STATUS_LOGGEDIN_OR_RECENTLY_LOGGOUT
* Store low guid for loggedin player or recently logout into WorldSession.
