Support filtering based on dynamic property comparisons

[Eiromplays]

Hey,

I have a suggestion for a feature that could be nice to have in some cases. The idea behind it is that you can filter on two properties at the same time. Say for instance we have Score1 and Score2, currently we need to know the value of one of them to filter on it. With this new feature, it would be possible to perform operations like Score1 > Score2.

We want to give this to end users who may or may not be capable of writing code, and so some things that LINQ predicates can do, combined with your delicious syntactical sugar, would be both unintimidating and powerful enough to cover everyone.
