Core: Use new SpellInfo class in core. Sadly, this commit is not compatibile with some of the custom code. To make your code work again you may need to change:

*SpellEntry is now SpellInfo
*GetSpellProto is now GetSpellInfo
*SpellEntry::Effect*[effIndex] is now avalible under SpellInfo.Effects[effIndex].*
*sSpellStore.LookupEntry is no longer valid, use sSpellMgr->GetSpellInfo()
*SpellFunctions from SpellMgr.h like DoSpellStuff(spellId) are now: spellInfo->DoStuff()
*SpellMgr::CalculateEffectValue and similar functions are now avalible in SpellEffectInfo class.
*GET_SPELL macro is removed, code which used it is moved to SpellMgr::LoadDbcDataCorrections
*code which affected dbc data in SpellMgr::LoadSpellCustomAttr is now moved to LoadDbcDataCorrections
