DO NOT USE THIS CLASS, IT JUST HOLDS GENERAL INFORMATION for weapons, ammo, and item pickups.
The suspended flag will allow items to hang in the air, otherwise they are dropped to the next surface.
The NOPLAYER flag makes it so player cannot pick it up.
The ALLOWNPC flag allows only NPCs to pick it up, too
USEPICKUP - Player must be holding "use" to pick it up
STATIONARY - Cannot be moved around by force push/pull, radius damage, knockback, etc...

If an item is the target of another entity, it will spawn as normal, use INVISIBLE to hide it.

An item fires all of its targets when it is picked up.  If the toucher can't carry it, the targets won't be fired.

"wait"	override the default wait before respawning.  -1 = never respawn automatically, which can be used with targeted spawning.
"random" random number of plus or minus seconds varied from the respawn time
"count" override quantity or duration on most items.
"team" only this team can pick it up
	"player"
	"neutral"
	"enemy"

When picked up, will be used as a second saber unless:
	1) It's a two-handed saber
	2) The old saber was two-handed
	3) You set "saberSolo" to "1"
	4) You have 2 sabers and the saber pickup is on your right when you touch it

saberType - entry name from sabers.cfg - which kind of saber this is - use "player" to make it so that the saber will be whatever saber the player is configured to use
saberColor - red, orange, yellow, green, blue, and purple
saberLeftHand - always be added as a left-hand saber
saberSolo - set to "1" and this will be the only saber the person who picks this up will be holding
saberPitch - if set "LEANING" flag, you can specify the exact pitch to lean forward/back
count - how many you can pick up before it's removed (default is 1, -1 is infinite)
