Spawn teleport, repeated join item and crop trampling.

Hello, I love your plugin but i believe i found 3 minor bugs.

I use the plugin GSit in my server and it allows players to sit on top of each other, if a player is sitting on top of another and jumps down the void, the spawn teleportation built into EcoLobby does not work and they fall forever.
The second issue is related to the join item i set up, sometimes for some reason players have 2 instances of the same item in their inventory, they stack up. I have the clear inventory setting turned on and it happens when they relog, only sometimes though.
And lastly, even with break blocks disabled, players are able to trample crops, jumping on top of crops will break them, I wish I didn't have to use worldguard because this plugin is very complete but it's up to you if you want to prevent that.
Thank you, and keep up the good work, your plugin is awesome.
