Move `IResource` and implementations to Windsor and remove it here

[stakx]

This is a follow-up to #603 which concluded with the following suggestion by @jonorossi:

I think IResource and its implementations should move into Windsor, it is no longer used by MonoRail, ActiveRecord, etc like it used to be, only Windsor survived. Obviously needs a major version upgrade, so happy to just ignore it for now like other areas like logging and just focus on DP for now until next major version.

If the types actually get moved there, make sure the previous linked issue gets reactivated & moved there, too.
