Devlog #28: More item stuff

Hi, did some more work on the items today. 

I decided to use Lua scripts for the item logic, so I don't end up with like 20 different C# files for different items. It also means people can add their own items in, but I don't think that is super likely to happen anyway haha.

So the system for placing items is finished for now, and I also added in debuffs, so that a tripwire item can apply 'Immobile' to an enemy. This part doesn't actually work right now because I ran out of time, but tomorrow I will fix it. I'll also try to add in some other item, but I think tomorrow is going to be quite busy so I might have to stay up a bit again.

Okay, see ya!
