Updated mechanics to be consistent with live regarding how invisible breaks when the client is the target of a spell.
Invisible will drop whenever a client is hit with a detrimental spell, regardless of if resisted, if it does damage or AOE.
Hide skill now also follows the same rules as above.
Implemented support for Rogue AA - Nerves of Steel which gives a chance for hide NOT to break
when client is hit with an AOE spell.
* removed the double level gain messages to display once either the level gained or the level.
* implement the message "You will now lose experience when you die" and "Your items will no longer stay with you..." when reach a certain level already sets in the rule table.
via accounting for differences in attacker/target size. This
fixes a very common issue of player hitting range attack and
nothing happening due to server improperly calculating
max range.
This is handled by client under normal conditions, however if you
force cast this effect in situations like 'procs' you can cause
zone crashes, therefore a failsafe check is added in 'SpellOnTarget'
