[FilterScript] Advanced Spectate System

* Smart checks in place to protect issues happening upon initially spectating. [93-109]
* Grabs the following data to later replace when done spectating, listed in order as placed in code:

• Player Weapon Data ( each slot's weapon and ammunition )
• Player Health
• Player Amour
• Interior and World
• Vehicle Information, if pertains (vehicle ID, seat ID, vehicle position )
• Player Position, if on foot
• Name of whom Spectating

* Smart checks upon exiting spectator's mode and spawning - regarding health, armor, weapon, and vehicle data
* If whom you are spectating dies, it waits for the player to respawn, then initializes spectation
* If whom you are spectating disconnects, spectation ends
* If whom you are spectating goes from on-foot -> vehicle or vice-versa, spectation standards are adjusted accordingly
* If a player's interior changes, spectation standards adjust accordingly
( Note: Sometimes SA-MP doesn't fully adjust it's spectation mode. Interior & World IDs will match, but not update on screen.
Resulting in a blank spectation. Simply respectating fixes this issue. )
* If a player enters a checkpoint, it will adjust spectation standards accordingly
* You may use your mouse to switch through online players to spectate ( LMB = +1 || RMB = -1 )


There are specific things I had placed into this for the purpose of being able to test the script, but can also come in hand for some. They are listed with their purposes below:

* If you have MAX_PLAYERS already defined, you may remove the definitions up near the top.
-- Some don't have this correctly defined, or want to guarentee their MAX_PLAYERS within the filterscript.
* Change p_adminlevel to your admin level variable if you want it to be restricted to administration.
-- If you plan to restrict this to adminstration, replace 'p_adminlevel' to your administration variable for players.
* Change admin_duty to your admin on duty variable if you have one.
-- If you have a godmode command for administration, replace 'admin_duty' to whatever your variable is that checks if it's enabled or disabled.
