Somewhat tidied up looting. Closes #55.
Merge branch 'master' of https://github.com/twostars/snoxd-koserver
Removed a (now) unnecessary variable.
Looting: The packet is now sent to notify players when the item was given to someone else in their party.
Magic system: Fixed a NULL pointer crash in ExecuteType4().
Magic system: Removed an unnecessary copy operation when using Unit::AddType4Buff().
Magic system: Simplified type 4 buff iterator usage & optimised some caster logic that was being handled for each target in ExecuteType4().
Magic system: Clarified the buff/debuff logic, replaced the now useless m_bType4Flag.
Magic system: Clarified the logic further with inline methods (isBuff(), isDebuff()).
