Try talk "difficulties" on the talk descriptions?

[CodeFoodPixels]

This was something that was debated and was added here as something to potentially try.

Adding a "difficulty" rating to the talks so that people know what sort of depth the talk will be. One argument for this was that people could know that it's not going to be something that's just going over stuff they already know. An argument against it was that people may exclude themselves thinking it was too advanced for them when it may be fairly easy to get a grasp on.

My personal view is that it's worth a shot and we can refine or discard it if we find it's not working.
