Fixes #456

There's a few things missing here - I would suggest including the following in this PR, but if you don't want to do them in this PR just make sure open issues for them so we can keep track:

• Needs async ticking option as we have for blocks
• Needs error handling (we have error handling set up for other entity interfaces)
• Currently you're using a getter for tickDelay, but the convention with these sorts of interface variables is to use setTickInterval and setAsync and so on. The reason for this is to avoid having loads of getters for trivial properties which became quite a problem especially w/ the fluid stuff. It should hopefully be fairly straightforward as you can replicate what ticking blocks do.

(also docs :P - you can just do something similar to the block tickers for this)
