Restructured codebase to introduce a new layer of organization, and to begin mass refactorization of Do.Addins (and core) into separate assemblies.

        * Do.Platform: platform-neutral codebase to be used by non-interface plugins and core. Plugins that only use code from this assembly are cross-platform.
                * Do.Platform.UniverseFactory: create abstract items, like Applications (IApplicationItem) and Files (IFileItem).
                * Do.Platform.*: Platform-neutral logging, preferences, other utilities.

        * Do.Platform.Linux: Linux-specific implementations to be used by classes in Do.Platform. Plugins that use code from this assembly are Linux-dependent.
