Require Dependancies OR case

[Wrench36]

Very happy with your work on this project.
I'd like to request a feature, though.

I'd like to be able to define dependencies using an "OR" case, i.e.
"This mod requires A or B".

My specific use case is I have two versions of a mod and some people prefer one over the other, but I'd like to require the user has one of them installed.
