Game server/skill system: removed the explicit region checks from CMagicProcess::UserRegionCheck() as it accepts units from surrounding regions. Also cleaned up the range check.
AI server: implemented a crude casting state for delayed casting of skills (e.g. guard tower arrows), instead of blocking the thread (still needs to be rewritten though).
Game server: fixed a typo with RLB's max level requirement. Closse #268.
Shared/config: INI files are now saved universally without a carriage return (all for Notepad! Traitor!).
AI server: corrected the return types of CNpc::Attack() & CNpc::LongAndMagicAttack().
AI server: target ID's now correctly set when AI must wait on a casting animation; resolves #269.
Game server: players now respawn near the Arena NPC when they die in one of the Moradon arenas. Resolves #266.
Game server: updated Moradon arena respawn coords to center on the official respawn point (which isn't actually randomly placed officially, but nevermind).
Game server: players are now kicked out of zones they no longer meet the level requirements for.
