*
*	Description:
*		This plugin basically provides an ability to spawn HL healthkits.
*		If healthkit is collected it would appear again later like in HL.
*		Note: Engine module required.
*
*	Commands:
*		healthkit_spawn [save] - spawns a healthkit at the origin of a player who typed that command
*			if "save" argument is specified then origin would be added to the end of the file
*			$configsdir/maps/<currentmap>.cfg (file would be created if it is not exists)
*			that would allow to spawn saved healthkits every specific map load
*			Note: to avoid error create $configsdir/maps folder if it is not exists.
*
*		healthkit_load <x> <y> <z> - spawns a healthkit at the specified origin
*
*		healthkit_clear - removes all spawned healthkits
*
*		Commands access level is ADMIN_CFG (falg "h") can be redefined (#define ACCESS_LEVEL)
