* Save temporary unsummoned pet to current slot (instead non_in_slot mode) and
prevent save as current pet summoned while temporay unsummon (arena)
* Prevent overwrite temporary summoned pet data
* At player loading set temporary unsummoned pet data instead pet loading
if pet expected to be temporary unsummoned in current player state (loading in taxi flight/etc)
* Restore proper pet at arena leave and unsummon in arena summoned.
Problem exist from client version switch when stable slot amount changed.
In result this has been source problems with stable use (3-4 slots) and possible pet lost in some cases
or "not save state" for summoned pets.
Use enums to avoid repeating problem, use more safe value for not-in-slot save (for summoned pets)
Fixed data preparing for MSG_LIST_STABLED_PETS.
this is done by this script:
ack -c "World.h" | ack :1 | sed 's/:1//' | xargs grep -c sWorld | grep :0 | sed 's/:0//' | xargs sed -i '/#include "World.h"/d'
i didn't checked every change but gcc haven't complained
* Mark spells learned in result character creating, another spell learning, skill grow,
quest reward as dependent and not store its in `character_spell`.
* Prevent re-learning known spell in expected state
* Prevent re-learning low rank spell as active if higher rank known.
* New type of non-stacked ranked spells check: skill dependent spell bonuses.
* Activate (show propetly and cast if need) lesser spell rank
for non-stackable in spellbooks spells at unlearn high rank
Including fix _SCallback for 3 params, triggred mode correct call for .cast back and .cast target.
Remove outdated code for support old 19421 (and ranks) implementation in client data.
