Zombie Spawn

Zombie spawn .
This plugin I wrote for myself but maybe it'll be useful for someone else.
This plugin allows your to create you own spawn points for mobs.
Config.yml

• delay - the delay between mobs spawn in seconds
• tostart - the delay between mobs spawn on server start in seconds
• maxamount - maximum amount of entites in your single spawn.
• radius - radius of the spawn point in which mobs will spawn
• entitytype - type of mobs which will spawn
• only_one_item_to_drop - if true then will drop only one type of item from dead mob
• monsters - mobs from which given items will drop
• items - here you can customize items which will drop from given mobs, you can set the chance of drop, the name of item after drop, amount of items and the type of items( necessarily correct spelling)
• commandslist - do not need to change, it is just available commands
• spawns - there are your spawn points

So how to set the spawn points, you need to write the command:
/zombie newspawnpoint <name>
To remove the spawn points you need to write the command:
/zombie removespawnpoint <name> .
To reload config:
/zombie reload
To see all available command in game you need to write the command:
/zombie list
To see all of your spawn points you need to write the command:
/zombie spawns
Clear zombie counter's in all spawns to 0:
/zombie clear

Zombies and Skeletons do not burn on the sun!

This plugin cannot be perfect. I've been writing plugins for minecraft only for one week of my life. If you find bugs let me know and I try to fix it and also give any idea what kind of feature I need to add.
Thanks.
