Fixed minor typos.

Static comparator to prevent initialization on each call.
List is created after single-target checks are performed.
Using LinkedList instead ArrayList due resize overhead.
Adding target only if it's not null.
Sorting the list of creatures after it's complete, not after adding the
target (that wouldn't have an effect on the list since it has a single
element).
Performing maximum target check first.
Skipping hidden creatures.
Skipping, when in siege, creatures that are not in the same siege side.

Fix #293

Moving all files to main folder.
Using Gradle to define, manage dependecies and build the project.
Upgraded Gradle wrapper.

	* Complete rework of !CharEffectList.
		* Mimicking "List" operations, remove(..), add(..), isEmpty()...
		* Thread-safe.
			* Using reentrant locks for read/write operations.
		* Removed cache-array, wasn't working.
		* Removed useless methods.
		* Removed queue, wrong implementation was leading to wrong updates in effect lists.
		* Now effects from skills are managed in batches, less calls to methods, avoiding overhead from synchronization and keeping abnormal type groups safe.
		* Support for blocked buff slots, no more hacks!
			* Implemented proper effect.
		* No more dependence on Javolution.
		* !JavaDocs!
	* Abnormal type, level and time are global to the skill and not specific to each effect.
		* Keeping support to customize each effect duration time, needs testing.
	* Added abnormal type enum, no more strings.
		* Removed overhead from string comparison.
	* !EffectTemplate rework:
		* No more public fields, we use mutators and accessors to work with them!
		* Func list to List instead of array.
			* Avoid CPU overhead, System.arraycopy(..).
		* Removed unused transform parameters.
		* !JavaDocs!
	* L2Skill rework:
		* No more dependence on Javolution.
		* Func and Effect lists to List instead of array.
		* Removed some useless effect type related method from skills.
		* Removed custom restriction for stolen effect with current duration less than 5 seconds.
		* If NPE appear they have to be properly fixed, no more hacks!
		* Updated toString() method.
		* !JavaDocs!
	* L2Effect rework:
		* Effects do not store static data from template!
		* Removed unused transform parameters.
		* Removed "passive effect" related methods, effect is passive if skill is passive.
		* Removed "buff"/"debuff" related method from effects, skills are buffs or debuffs not effects.
		* Updated toString() method.
		* Removed effectCanBeStolen() method, now canBeStolen() is overridden in effect implementations in Datapack.
		* !JavaDocs!
	* L2Item minor rework:
		* Func and Effect lists to List instead of array.
			* Avoid CPU overhead, System.arraycopy(..).
		* No more dependence on Javolution.
		* Now _questEvents is initialized only if it's used, not for all items!
	* L2Weapon fixes:
		* Fixed bug in getSkillEffects(L2Character, L2Character, L2Skill) returning always empty array of effects!
		* Func and Effect lists to List instead of array.
			* Avoid CPU overhead, System.arraycopy(..).
		* No more dependence on Javolution.
	* Reworked "get func" methods to avoid toArray(..) calls.
	* Proper use of maps, no more iteration over keys and retrieving the value using get method.
	* Externalized formula to calculate current effect duration to Formulas class.
	* Static fields are upper case.
	* Adding button to reload effects, '''must be follow by skill reload and probably player restart''' to ensure there is no memory-leftovers.
	* Fixing skill Frintezza's Songs(5008) abnormal types.
	* Fixing minor bug with High Five GM skills.
	* Added name to effect list from admin panel, fixed other minor glitches.
	* Removed old and classing GM menu.
	* Updated logs and comments.
