/*QUAKED func_breakable (0 .8 .5) ? INVINCIBLE IMPACT CRUSHER THIN SABERONLY HEAVY_WEAP USE_NOT_BREAK PLAYER_USE NO_EXPLOSION
INVINCIBLE - can only be broken by being used
IMPACT - does damage on impact
CRUSHER - won't reverse movement when hit an obstacle
THIN - can be broken by impact damage, like glass
SABERONLY - only takes damage from sabers
HEAVY_WEAP - only takes damage by a heavy weapon, like an emplaced gun or AT-ST gun.
USE_NOT_BREAK - Using it doesn't make it break, still can be destroyed by damage
PLAYER_USE - Player can use it with the use button
NO_EXPLOSION - Does not play an explosion effect, though will still create chunks if specified

When destroyed, fires it's trigger and chunks and plays sound "noise" or sound for type if no noise specified

"targetname" entities with matching target will fire it
"paintarget" target to fire when hit (but not destroyed)
"wait"		how long minimum to wait between firing paintarget each time hit
"delay"		When killed or used, how long (in seconds) to wait before blowing up (none by default)
"model2"	.md3 model to also draw
"target"	all entities with a matching targetname will be used when this is destoryed
"health"	default is 10
"radius"  Chunk code tries to pick a good volume of chunks, but you can alter this to scale the number of spawned chunks. (default 1)  (.5) is half as many chunks, (2) is twice as many chunks

Damage: default is none
"splashDamage" - damage to do
"splashRadius" - radius for above damage

"team" - This cannot take damage from members of this team:
	"player"
	"neutral"
	"enemy"

Don't know if these work:  
"color"		constantLight color
"light"		constantLight radius

"material" - default is "0 - MAT_METAL" - choose from this list:
0 = MAT_METAL		(basic blue-grey scorched-DEFAULT)
1 = MAT_GLASS		
2 = MAT_ELECTRICAL	(sparks only)
3 = MAT_ELEC_METAL	(METAL2 chunks and sparks)
4 =	MAT_DRK_STONE	(brown stone chunks)
5 =	MAT_LT_STONE	(tan stone chunks)
6 =	MAT_GLASS_METAL (glass and METAL2 chunks)
7 = MAT_METAL2		(electronic type of metal)
8 = MAT_NONE		(no chunks)
9 = MAT_GREY_STONE	(grey colored stone)
10 = MAT_METAL3		(METAL and METAL2 chunk combo)
11 = MAT_CRATE1		(yellow multi-colored crate chunks)
12 = MAT_GRATE1		(grate chunks--looks horrible right now)
13 = MAT_ROPE		(for yavin_trial, no chunks, just wispy bits )
14 = MAT_CRATE2		(red multi-colored crate chunks)
15 = MAT_WHITE_METAL (white angular chunks for Stu, NS_hideout )

SOLID - Movement is blocked by it, if not set, can still be broken by explosions and shots if it has health
AUTOANIMATE - Will cycle it's anim
DEADSOLID - Stay solid even when destroyed (in case damage model is rather large).
NO_DMODEL - Makes it NOT display a damage model when destroyed, even if one exists
USE_MODEL - When used, will toggle to it's usemodel (model name + "_u1.md3")... this obviously does nothing if USE_NOT_BREAK is not checked
USE_NOT_BREAK - Using it, doesn't make it break, still can be destroyed by damage
PLAYER_USE - Player can use it with the use button
NO_EXPLOSION - By default, will explode when it dies...this is your override.

"model"		arbitrary .md3 file to display
"health"	how much health to have - default is zero (not breakable)  If you don't set the SOLID flag, but give it health, it can be shot but will not block NPCs or players from moving
"targetname" when used, dies and displays damagemodel, if any (if not, removes itself)
"target" What to use when it dies
"target2" What to use when it's repaired
"target3" What to use when it's used while it's broken
"paintarget" target to fire when hit (but not destroyed)
"count"  the amount of armor/health/ammo given (default 50)
"gravity"	if set to 1, this will be affected by gravity
"radius"  Chunk code tries to pick a good volume of chunks, but you can alter this to scale the number of spawned chunks. (default 1)  (.5) is half as many chunks, (2) is twice as many chunks

Damage: default is none
"splashDamage" - damage to do (will make it explode on death)
"splashRadius" - radius for above damage

"team" - This cannot take damage from members of this team:
	"player"
	"neutral"
	"enemy"

"material" - default is "8 - MAT_NONE" - choose from this list:
0 = MAT_METAL		(grey metal)
1 = MAT_GLASS		
2 = MAT_ELECTRICAL	(sparks only)
3 = MAT_ELEC_METAL	(METAL chunks and sparks)
4 =	MAT_DRK_STONE	(brown stone chunks)
5 =	MAT_LT_STONE	(tan stone chunks)
6 =	MAT_GLASS_METAL (glass and METAL chunks)
7 = MAT_METAL2		(blue/grey metal)
8 = MAT_NONE		(no chunks-DEFAULT)
9 = MAT_GREY_STONE	(grey colored stone)
10 = MAT_METAL3		(METAL and METAL2 chunk combo)
11 = MAT_CRATE1		(yellow multi-colored crate chunks)
12 = MAT_GRATE1		(grate chunks--looks horrible right now)
13 = MAT_ROPE		(for yavin_trial, no chunks, just wispy bits )
14 = MAT_CRATE2		(red multi-colored crate chunks)
15 = MAT_WHITE_METAL (white angular chunks for Stu, NS_hideout )

set size better?
multiple damage models?
custom explosion effect/sound?
