void SpecialAbilityUpdate::update( void )

This is the brains of the entire special ability update. There are several optional steps and
variations that can be processed for any particular type of special ability. A special ability
that has every option will do the following in order:

	1 -- APPROACH: If I'm not close enough to the target, then approach it
	2 -- UNPACK: If I need to unpack before I can prepare, then do so now (this uses the model
			 condition unpack).
	3 -- PREPARE: If I need to perform a task for a period of time before I can trigger my special
			 ability, then do so now. A good example is aiming with a targetting laser for a few 
			 seconds before firing your special weapon.
	4 -- TRIGGER: Once preparation is complete, fire your special ability now.
	5 -- PACK: If I need to pack after finishing my attack, do so now.
	6 -- FINISH: Clean up the states, and turn off the update.

Variations:

	Persistent Specials -- A persistent special will continually trigger it's effect every so often
		 and never end. A good example of this is the disable building hack. The hacker will run up
		 to the target building, unpack, prepare (firing hack stream), then after a period of time,
		 the building becomes disabled. But because it's persistent, we reset the preparation and 
		 trigger the building disabled code over and over again -- which is on a timer.
	No Target Specials -- You can link two different main specials together. Colonel Burton has the
		 ability to lay C4 charges on multiple targets. Activating these specials require a target.
		 The non-target version is actually the detonator, which goes through all the special objects
		 and detonates each one of them.

Options:
	SpecialPowerTemplate -- Defines the special power template that links to a command.
	StartAbilityRange		 -- Specify how far you want your unit to be from the target before
													start your special ability.
	AbilityAbortRange		 -- After starting an attack, it'll allow preparation unless the target goes
	                        beyond this range. If this happens, the ability is aborted outright.
	PreparationTime			 -- How long it takes to prepare your special once in position and unpacked.
	PersistentPrepTime	 -- This value defines whether or not you are using a persistent special. 
													Once the special ability is triggered, it'll wait until this specified
													delay occurs and it'll trigger it again, for ever until the unit dies, 
													the target dies, or the unit decides to do something else.
	PackTime						 -- How long it takes to pack up the unit after triggering a non persistent
													special ability or after ordering the unit to do something else, or the
													target dies (if applicable).
	PackUnpackVariationFactor -- Randomizes the pack and unpack time by specified range. The closer
													to zero, the smaller the variation. 0.2 would have a pack or unpack range
													of xTime +/- 20%. This is important because it represents averages.
	UnpackTime					 -- Same as PackTime, except used once entering range of target.
	SkipPackingWithNoTarget -- This option is used by the No Target Special variation, and only uses
												  packing/unpacking when you have a specific target. In the case of Colonel
													Burton, this value is set to true. When he plants a C4 charge, he has a
													target, therefore he requires unpacking (laying the charge). When he runs
													away and decides to detonate the charge, he calls the same special
													ability, but without a target -- therefore the packing is skipped and
													detonates it right away.
	SpecialObject				 -- Defines the special object the unit will create via the special ability.
													In one case, it creates and maintains the laser or binary stream during
													preparation. In Colonel Burton's case, it keeps track of the C4 charges
													that he has placed.
	MaxSpecialObjects		 -- Defines the max number of special objects that can exist at any given
													time. The laser example only has one, but the C4 charges can have more.
	SpecialObjectsPersistent -- If this flag is set, then the objects will remain should the owner
													decides to do something else... C4 charges are a good example.
	EffectDuration			 -- Defines the duration of the special ability. In the case of disabling 
													the building (hacker), this value will dictate how long the building
													will be disabled should the hacker die or stop the attack.
	UniqueSpecialObjectTargets -- Prevents the owner from placing multiple special objects on the
	                        same target. C4 charges once again.
	SpecialObjectsPersistWhenOwnerDies -- If the owner dies, the special objects will remain in
													the world. Timed C4 charges is a good example, but remote C4 charges
													is a bad example -- because it requires the owner to detonate them.
	FlipObjectAfterPacking -- Simply rotates the object 180 degrees after packing (due to special
													animation case).
	FlipObjectAfterUnPacking -- Simply rotates the object 180 degrees after unpacking (due to 
													special	animation case). Used by colonel burton after planting charge.


	Lets use the Age of Kings Trebuchet as a simple example:
	Variation -- PersistentPrepTime (set to true in ini file)
	1 -- APPROACH:	Get within range before unpacking
	2 -- UNPACK:		Unpack the treb at this location.
	3 -- PREPARE:		Aim at the target
	4 -- TRIGGER:		Fire the treb.
	5 -- RESET PREPARATION:	Go to step 3 until target dead.
	6 -- PACK: Assuming we are done... pack up
	7 -- FINISH: Stop the special ability
