* optimizations on Spell
- cooldown and groupCooldown are now correctly working
- vocation supports several vocation strings now
ex: :vocation("sorcerer;true", "master sorcerer") will show "sorcerer" in description
* Spell handling through lua
- Basics are done, but this is still wip
* work on reload for spell
- just a few tiny changes
* spell __newindex function
- this include __newindex for spell
- Spell does now return Userdata instead of tabledata
* added Spell Functions
- It includes all necessary Spell functions now
* made use of dynamic_cast
- There is still a cleanup todo, there are still several const_cast which I need to switch over
- applied createFunctions for Spell
* added a few safety checks
- cleaned up some functions
- changed const_cast to dynamic_cast
- exclusive InstantSpell & RuneSpell functions will not crash the server if not used appropriate
* erased duplicate
- erased duplicated g_spells->clear(true);
* enabled strings on Spell creation
- now you can use Spell("rune") & Spell("instant") aswell
* shortened down luaSpellGroup
- created stringToSpellGroup(), so I could get rid of repetitive stuff.
* combined charges and hasCharges
- if we set a rune :charges(1) or higher it'll automaticly mean that it should use charges aswell.
However if we don't set :charges or :charges(0) it means the rune is infinite.
* Final Spell handling
- changed so Spells are getting pushed as Spell now and not as InstantSpell or RuneSpell
- corrected the methods :allowFarUse :blockWalls and :checkFloor
- corrected RuneSpell* Spells::getRuneSpell(uint32_t id) it now can be accessed by either runeId or spellId
- corrected InstantSpell* Spells::getInstantSpellById(uint32_t spellId) it now returns the correct InstantSpell
* compiler error fix
* little update
- removed switch since it's just SPELL_INSTANT and SPELL_RUNE anyway
- changed RuneSpell* Spells::getRuneSpell(uint32_t id)
so it doesn't try to re initialize it again
* Spells #example.lua
- added Spells #example.lua
* safety move
- moved those 2 variables inside the if statements for safety.
