Fully rewritten the script, no more Runnables at all.
Fixed the untargetable Beleth.
Includes retail like fix - only real Beleth cast horn of rising.
Includes retail like fix - all Beleth dissapear for 60 seconds only if
the chosen one gets killed, and not the opposite like it was.
Npcs are properly spawned / deleted whenever needed.

Notes:
Cameras are probably a bit wrong, they are too low on floor and
sometimes you see sky because of that.
Removed that part with broadcasting of Missing Text, at least until
someone would get the real text they should broadcast with proper
conditions... (if any at all).

BETA: Fixing all grand boss respawn timers now they will be hour by hour instead of milisec to milisec which means if you kill a boss at 12:18 it will respawn at XX:18 not totally randomly as before.
	* Reported by: Tryskell

	* Proper GPLv3 license.
	* Updated all Java DP files.
	* Added missing license to the following files:
		* !FirstClassTransferTalk
		* !AdminInstanceZone
	* Updated Eclipse preferences for new files (header).
		* ''Same'' settings as Core.

	* Do not use SkillTable.getInstance().getInfo(id, level) instead use SkillHolder DTO.
		* Is possible to change the underlying implementation without reworking every single script.
		* Avoids some problems during reloading.
	* Static final variables should be upper case.
	* Minimize the use of @formatter:off
	* Use arrays of Location instead of arrays of arrays of int.
	* Don't use literal values in the middle of the code, use static final variables for Ids, levels and other values.
	* Document the code when something is not finished/retail like.
		* When you work in open source is important to note that you knew it wasn't finished and let others know it as well.

	* All scripts extending AbstractNpcAI instead of L2AttackableAIScript.
	* All static variables to upper-case.
	* All constructors moved just after variables and private instead of public.
	* Initiating script with new Script(Script.class.getSimpleName(), "ai") instead of new Script("Script", "ai")
	* Removed useless checks example addKillId(123) onKill() if (npc.getNpcId() == 123).
	* Moved registerMobs method into AbstractNpcAI.
	* L2AttackableAIScript is now final please do not extend it anymore.
	* Cleanup

1. Within !AdminBan.java:
- '''(Style)''' String.equals("") is now replaced with String.isEmpty().
(Avoid bad practice of returning true/false based on equating a String, instead use the strings length.)
2. Within !BeastFarm.java, !EnergySeeds.java, !FeedableBeasts.java:
- '''(Clean Up)''' Organized imports.
3. Within ''Beleth.java'':
- '''(Clean Up)''' Formatted to adhere to L2J code style.
- '''(NPE)''' Within public void run(), there is a check to see if _npc is null or not, yet _npc.getAi... is outside this check. If _npc was indeed null, a null pointer exception would have occured.
- '''(NPE)''' Within private static void deleteAll(), there is a check to see if minions is null or not, yet minions.clear() is outside this check. If minions was indeed null, a null pointer exception would have occured.
- '''(Style)''' Initialization of static field's spawnTimer and belethKiller are now set by a setter i.e getters and setters.
(Avoid writing to static from instance method's and bad initialization practice.)

	* Other warnings will be fixed later.

	* Avoiding synthetic access.
	* Avoiding potential NPEs.
	* Minor JavaDocs fixes.
	* Added some TODO tasks.

		1. Items with consume count won't be consumed without giving the reward.

		1. Unhardcoded system message for item reward.
