Construct 2 Release r205.2

This is a minor update mainly to fix an editor crash that could occur when interacting with the Object Bar. There was also some light refactoring of runtime code which is not in the changelog since it doesn't functionally affect anything, but hopefully that did not break anything either. As before please test carefully and hopefully we can have a stable update out soon.
